1.) Most liked Land Before Time Character - Cera; though I thought she was at her best in the first movie (until the end where she redeems hereself, she's this irreverent, smack-talking little chump that I think is a really entertaining character - though, in the context of the first movie alone, I prefer Ducky), I think that she shines in her arc in the eleventh (only in the arc in the eleventh, I don't like how she's handled outside of it) and twelfth movies. I'm also fond of Topps (as an antagonist in the earlier movies, and more genuinely after
X) and Etta.
1.5.) Most liked Land Before Time Sharptooth - Coming up with a category to say that I love Sharptooth himself - I don't think he's "evil" per-say, but he's this unstoppable, ferocious, terrifying force of nature that no other antagonist in the series - either predatory animal or proper villain - can even get close to matching.
2.) Least liked Land Before Time Character - Ignoring the obvious answer (the yellowbellies/Doofah), I don't like Dana and Dinah from the sixth movie at all; way too loud, way too squeaky and indistinguishable from one another character-wise; I don't want to dwell on negativity here, so moving on.
2.5.) Least liked Land Before Time Character - The tyrannosaurs from
The Great Longneck Migration are laughable; gone are the days of jumping onto the backs of sauropods and leaving devastating wounds, this is a new era -
our Rexes can be tripped by tiny little longnecks and don't leave so much as a mark when biting peoples' legs.
3.) Most liked Land Before Time song - "If We Hold On Together"; I don't think this is a very fair contest, though. Runner-ups are "Always There" and "Best of Friends".
4.) Least liked Land Before Time song - The less said about "Imaginary Friend", the better.

5.) Most liked Land Before Time film -
The Land Before Time; I don't think it's perfect, but it's still a great, great movie.
Journey Through the Mists is also pretty good.
6.) Least liked Land Before Time film - Though
The Great Valley Adventure and
Journey to Big Water come close, I don't think there's any topping
The Wisdom of Friends here.
7.) Most memorable Land Before Time moment - As odd and specific as this may be, the part of any of the movies that has stuck out to me the most is a brief shot during the earthquake scene in the original movie, where Sharptooth rears up on his hind legs, standing on a loose rock, surrounded by steam. I don't know exactly why this shot stood out to me so much since more first viewing of the movie, but, it did.
