Being as I have now seen all of the movies (along with 3 episodes of the TV series), I am ready to give this a second go. So...
1. Petrie, followed by Ducky. I'm threatening to put Ruby on the list as well, but I'll have to wait for that. Anyways:
Petrie is...well, to put it simply, just plain fun. I knew he would be my favorite character when I viewed the first movie last year. Oddly enough, he happens to be the reason why I love Land Before Time in the first place. Although he may not be very self-confident at times, he shines when he really needs to, and like almost everyone else, he is very loyal and trustworthy to his friends, both of which I can relate to. I also love his squeaky voice and cute giggle of his. Plus...am I one of the few members here who actually likes hearing him sing? Let's not forget the fact I can pull off a good impression of him, as well as some other characters. I could go on and on, but I'll stop here.
As for Ducky, what can one say about her? She is a very cute character who can lighten up anyone's spirit when needed. Who could ever forget her "yep yep yep" catchphrase? Plus, the term "Damsel in Distress" seems to fit best for her, as she seems to be the "perfect" character in most cases.
2. It's pretty tough to choose, but there are a few:
Shorty (at first) and (to a much lesser extent) Cera, mainly because...well, let's face it, I hate braggarts. Shorty pretty much acted like a punk when he first appeared, but toward the end, we could clearly see why. Cera shows confidence when she needs to. Sure, she can be a bit arrogant (particularly in movie eleven *cringes*) and attempts to show that she is fearless when she really isn't, but at the same time, she is very brave. Mr. Threehorn is listed as well, for obvious reasons.
Ozzy from movie two is also a good example, particularly because I feel it was wrong to treat his sibling as if he were a slave. Sure, Ozzy wants to eat eggs and Strut wants to eat greens, but having Ozzy command his own brother to stick to his own diet? Wrong in my book.
3. If We Hold On Together, Always There, Standing Tough (to an extent), No One Has To Be Alone, Bestest Friends, The Lesson, Things Change, and many more.
4. Frankly, I don't hate any song in the movies. However, if I had to pick one, it would be Imaginary Friends, mainly because of the fact that the song had little to no impact on the plot, though it has grown on me since I first posted here.
5. First movie always wins. For sequels, a three-way tie between movies 7, 9 and 10.
6. 13; not because of the yellowbellies (whom, yet bizarre, are actually not that bad to an extent), but because I felt that barely anything happened in it. It simply happens, then it's over. To me, this situation is quite awkward. I can tell why the franchise was killed after this.
7. Everything about the first movie, basically.
Aaaaand that's all. I hope to do one more take when I've seen all the episodes of the TV series.
