Hmm come to think of it, for me PERSONALLY , all of the gang have been annoying at times throughout the franchise. I mean I find Petrie's voice a wee bit annoying at times, there's Littlefoot been winey in most of the 5th film, and Ducky is quite winey too in the 8th film, and as much as I love Cera, her Mad song in the 8th film was dreadful in a annoying sort of way.
Bit still I like all of the gang and when they are annoying it's not to a point of disliking them
But characters I do find annoying and are in my list are the following.
NOTE* I don't have a top 10 but here they are.
Hyp
Nod
Mutt
Rhett
Shorty
the yellow bellies (even though I've only seen clips from the 13th film)
Dinah and Dana. I found them annoying from the second they came into screen and onto Cera's head. All they did was arse around, talk gibberish, and make a fool out of Cera and get her in trouble off her dad. Give me Tricia any day!
But Cera's dad aka Topsy is the number one character that dose my head in.
I said this in another topic but he's one of the worst dad's I have ever seen in media.
I mean in the 3rd film there's him been a control freak over the water, finger pointing at Littlefoot for wasting water, endangering Cera's and his own life to escape the fire......
In the 5th film he finger points Littlefoot again....
In the 6th film he bosses Cera around about looking after bloody Dinah and Dana.
In the 7th film doing the old I'm not angry I'm furious thing when he starts blaming the kids about Pterano....
If I were a character in the LBT world I'd most likely give him a run for his money and be throwing a lot of 4 letter words at him. When Cera's not around that is.
I wouldn't put Topsy as worst dad in media or even LBT for that matter. What about Bron? Where the heck was he all those years? That excuse is as bad as some politicians's!!!!
Also, I dislike the Old One. She seems pretty uncaring about Grandpa Longneck and even is going to kill Chomper, even after he begs her not to and she knows there is something different about him. (Also Chomper is my favorite character and I find any attempt to harm him to be cruel. )
I dislike Dana and Dinah as they made me feel sorry for Cera and they are SO annoying.
I kind of dislike Rinkus as, though he's a kind of good villain, his appearance makes him dorky whereas Sierra's says "I am evil and I'm proud!"
I dislike Rhett as he is a nasty liar and bossed Ali around and also is now a figure I'm going to have to deal with if I want a Littlefoot and Ali romance.
Topps. I really hated him for years. I almost chalked him up to a sort of villain in film 3. (Ramming that guy over water! Come on man! And your fire escape plan almost got you and your daughter killed!) After seeing him be nicer after marrying Tria, I stopped hating him. (Especially when Tria bosses him around in film 12. Love that! True, he picks on Chomper in the TV Series with the tooth thing but Cera also helps grow Chomper's fears of Doc in the TV Series too.)
However, Topps doesn't win LBT's worst father award as that goes to Bron, a character who lives his pregnant wife and never bothers to come back for five years and then never bothers to go looking for Littlefoot, never brings his herd to the Great Valley so he can be with his son, and also isn't there for Shorty (who I also kind of dislike, though I blame his bad past and lack of love from Bron for his behavior like I blame Topps for Cera's behavior.) )
Also, and I can't quite say why it is in film VI, other than he never bothers to deflect Littlefoot from his hero worship thing or confirm whether or not he actually is the Lone Dinosaur, but I dislike Doc kind of too. Also, his treatment of Chomper is shameful and I totally agree with how Littlefoot, who hero worshiped him, was gonna cut all ties with him.
I also dislike those dinos from "Amazing Threehorn Girl" who seemed ready to banish Cera over her fib (a fib she kinda kept being urged into, mostly by Topps, but others too.) . Totally harsh guys!
