Original
Pros: Beautiful story, amazing animation, great score, and (generally) enjoyable for the whole family. The one that started it all. It's about overcoming obstacles, getting past prejudices, and most importantly: never giving up on your dreams.
Cons: It's about 20 minutes shorter than it SHOULD be. In fact, it's roughly the EXACT same length as Bambi, which I think is one reason why people call it the "dinosaur version of Bambi."
The Great Valley Adventure
Pros: It's a good follow-up to the original. It shows that the journey didn't have to end after the original feature.
Cons: While the first couple songs are okay, I hate Hate HATE "One Of Us Now!"

It gets stuck in my head, like most LBT songs, which are usually a guilty pleasure for me, but not that one. I used to love it, but now I just find it nonsensical and a bit annoying.
The Time of the Great Giving
Pros: This is actually a huge improvement to the second sequel, which while it wasn't horrible, it was a bit lackluster. This one has more drama than the second movie, almost near as good as the original.
Cons: I can't really think of many cons about this, other than the part where they scream "AAHHH!" is kind of annoying and pretty silly. But other than that, it's one of my favorite sequels.
Journey Through The Mists
Pros: I like the fact that they finally made a beloved character almost die from being sick. It adds an emotional twist to the story.
Cons: Like The Great Valley Adventure, it is a bit lackluster. Also, Grandma's Lullaby gets stuck in my head. >.<
The Mysterious Island
Pros: I like the fact that they finally made the dinosaurs leave the Great Valley and venture into the Mysterious Beyond for an extended period of time. Also, Chomper returns!
Cons: It's a bit overrated I think. This is kind of my own fault, but I've seen it too many times.

Also, Chomper's parents would probably have eaten the gang in real life.
The Secret of Saurus Rock
Pros: I like the spookiness of it. Many people are bothered by it, but I think it's an interesting story.
Cons: Can't really think of any. Once again, another favorite of mine.
The Stone of Cold Fire
Pros: We finally get to learn a bit more about Petrie's family, particularly his uncle. Also, Rinkus and Sierra are an interesting duo. I also liked the animation style. I know alot of people didn't, but I did for some reason.
Cons: I know I spoke about being realistic when speaking about number 5, I kind of wish that the Stone would have actually been magic. It would have made the story more interesting.
The Big Freeze
Pros: Unusual weather, eh? I thought it was cool (literally

) to finally see snow in the Great Valley, as well as the fact that the Great Valley itself is NOT perfect.
Cons: I thought the part where Spike falls under the ice at the end was kind of unnecessary. I mean, it was okay the first few times I watched it, but I think now that it seemed more like filler.
Journey to Big Water
Pros: We finally get to see some rain in the Great Valley. After watching Journey Through the Mists, I thought that the Great Valley NEVER got rain. Idk why

I always found the songs enjoyable, even the Imaginary Friends song. Petrie having a toothless sharptooth was actually kind of cute.

The best song is No One Has To Be Alone though. The "Boring" song is good too.
Cons: OMG Where do I BEGIN??!?!??? This is one of my least favorite movies, 2nd least fave only to 13. First of all, I hate how Littlefoot called Mo his "best friend" after only knowing him for 10 minutes.

Also, while Mo can be cute at times, he is kind of annoying. I was annoyed most by the part where he pretended to die only to freak them out. In half of the movie, the voice acting is HORRIBLE!!!!!!

The sentence "We can figure something out" said by Littlefoot to Cera has always bothered me. Also, the part at the end when they are grieving over Mo. First of all, I thought it was dumb to assume that Mo was dead just because he was being chased. Then, their little pity party after they thought Mo died had some pretty horrible voice acting as well. The Big Water reprise always gets stuck in my head and I HATE it

However, the thing about the movie that bothered me the MOST was the grasshoppers. That part was just stupid. They aren't SHARPTEETH FOR CRYING OUT LOUD!!!!!!!!!

There's PLENTY of bugs in the Great Valley I'm sure. One last thing, it's actually an error: In the closing credits, the "Boring" song is written out in some other language, which I never understood
The Great Longneck Migration
Pros: My ALL time favorite sequel!

Even my LBT-hating sister thought it was funny at times.

The best thing about this sequel is that it has a bit of continuity to the original feature, like the earthshake that separated Littlefoot from his grandparents. Also, I liked learning about Bron. Also, I like how Bron was called "Littlefoot" when he was younger, meaning that Littlefoot, while yes his name is cute for a YOUNG dinosaur, he won't have that name forever.

The sharptooth part followed by the "great circle" part was probably
Cons: The only thing that bothered me is that they didn't necessarily "Save the world" when all that really happened was a solar eclipse, but I guess that's because I already knew what a solar eclipse was when I saw this movie. Also, the fact that dreams are suddenly called "sleep stories" was kind of odd.
The Invasion of the Tinysauruses
Pros: I just LOOOOVE the tiny longnecks, especially Skitter! I've always just wanted to take home Skitter and keep him as a pet!!!!!!!

<3 I love him. His voice is adorable, and his name is cute too. I also like the story because the moral of the story is similar to the orignal as you should never judge someone because they are different, but this one is different in the fact that it means that you should never judge someone by their size. I also liked the whole Tria storyline. It finally showed the sweet side of Cera's father, or "Topsy." Tria was also a nice addition to the cast. There were quite a few LOL parts as well. It's the funniest movie in my opinion.
Cons: Nothing in this movie really bothered me. I thought it was pretty solid overall.
The Great Day of the Flyers
Pros: I loved the part where Mr. Threehorn/Topsy fell into the mud.

I also loved when Grandpa Longneck was like "I only wish Grandma could have seen it." I had no idea he had a sense of humor
Cons: I couldn't really find much to complain about here either.
The Wisdom of Friends
Pros: (as if there are any)

But yes there are a few. This movie means well in trying to teach lessons, or "wisdoms". While it fails at that, there are a few funny parts, like when Cera says "Here's a wisdom for you: DON'T EVER WAKE ME UP AGAIN!!!!!!!"

Cons: Do I even need to say it? Just about EVERYTHING was wrong with this movie! Littlefoot has turned into a party pooper. The animation is terrible. The part where Grandma Longneck falls off the edge in Littlefoot's dream bothered me for some reason. The yellow-bellies, while comical at times (and even sometimes reminiscent of the FAR more awesome Dory in Finding Nemo), are just annoying. The stupidest part of the movie is when you see the silhouette of Grandma Longneck at the end and they thought she was a sharptooth. In my opinion, it SHOULD have been a sharptooth, with the adults coming to save the day. Probably would have saved me from hating it so much.
Well, there you have it!
