Notably, Don Bluth himself stated that he couldn´t really view Sharptooth as a villain if he, indeed, was just a predator looking for food.
Also notably, the novelization expands Sharptooth´s role, and makes it very clear that he is anything but a predator desesperate for food, instead writing him as a vengeful and prideful killer who is only chasing the protagonists due to a grudge.
Michael Tavera's music in the sequels is amazing as well.
Big Lipped Alligator Moment: The scene with the baby pterosaurs fighting over a cherry; it's cute, but it serves very little to the plot, besides perhaps lightening the mood after Littlefoot's mother dies. The only part of the scene where they serve any purpose to the main characters is when the blue one tries to give his cherry to Littlefoot to cheer him up.
Designated Hero: Cera is, to put it bluntly, a selfish brat. She calls Littlefoot's mother "a stupid longneck", despite the latter saving both her life and Littlefoot's. And then there's the scene where Petrie falls into the tar and she ignores his screams for help. And she has no excuse for her actions other than being taught to behave this way from her equally jerkish father. Thankfully, shegetsbetter in the sequels.
Wasn't she trying to escape from a pack of "hard heads" or whatever they're called?
Then again she was not portrayed as a hero per se, but as a very flawed and even unpleasant person.
Everyone Is Jesus in Purgatory: In a particularly horrifying interpretation of the film. Click if you want to never be able to watch this movie again The earthquake near the beginning was a result of the Cretaceous–Tertiary extinction event, AKA the extinction of the dinosaurs. Meaning everyone was Dead All Along. The film is their journey through purgatory towards heaven, represented by the Great Valley. The dinosaur that comforts Littlefoot directly after his mother's death is an angel trying to get him to overcome his anger over his mother's death, for which he blames both her and (secretly) himself. The lava field is where Cera overcomes her sin of excessive pride, and where the rest of the group learns that there are no "shortcuts" to heaven, and that they must go on the path set for them, and have faith in it, or they'll never get there. The Sharptooth is representative of the kids' fear of their own mortality, and by killing him, they have finally let go of all of their earthly attachments, aside from Littlefoot, who still has guilt for the death of his mother. When he finally accepts her death, he finds the Great Valley, along with everyone else, where the rest of their families are waiting for them in the afterlife.
First Installment Wins: The original film is considered to be an excellent piece of work, even for adults... the musical sequels on the other hand tend to be quite disliked. Still, they have scores of fans and an entire forum, so they must have done something right.
He's Just Hiding: Some fans believe that Sharptooth actually survived his last encounter with the heroes and is still out there. Usually, they back this claim with the fact that, for the entire movie, Sharptooth was shown to be extremely durable, and survived other situations that should have killled him.
Moral Event Horizon: All the things that Sharptooth did and especially the murder of Littlefoot's mother become this if you realise through the book that he is in no way a Non-Malicious Monster led by mere instinct and knew perfectly well what he was doing.
Narm: A lot of the dialogue in this movie is very awkwardly written and sometimes awkwardly acted. You don't question it when you're a kid, but rewatching it as a teen or adult might give you a case of the bad laughs.
The Scrappy: Petrie, initially. Since his flanderization in the sequels, he bizarrely seems to have been received better, possibly simply due to being a reflection to what many think of the films.
Cera was also dangerously close to fall into this. While she was generally well-received by the critics, there were various viewers who were bothered by her attitude. It didn´t help the fact that she remained the most prejudiced and bratty of the characters, and even insulted Littlefoot´s mother despite the fact that she saved her life. Luckily (as it was said above) while still being the main character with the most attitude, in the sequels she Took a Level in Kindness, eventually becoming popular with many of the fans.
"Cera was too proud to admit (s)he'd gone the wrong way."
Additionally, ask people what gender Littlefoot is and you'll be surprised at how the answer varies. They drew girl eyelashes on Littlefoot. It doesn't help at all.
Ducky has to be the most obvious example; she can come off as a very expressive boy rather than a TomboyishGenki Girl.
What an Idiot: So Cera was really crazy enough to lead the others through an area with active volcanoes, rivers of lava, tar pits, all with only a little land to move around in when minutes earlier she complained to Littlefoot that his path was harder?
It's actually possible that Cera was going the right way seeing as Littlefoot's mother said they had to go through "mountains that burn".
It appears that the Littlefoot and Cera got turned around during their fight. The scene starts with Littlefoot pep-talking the group up a mountain, suggesting the Great Valley may be on the other side. Finding a barren wasteland valley at the top, Cera decides she's had enough and starts back down, preferring the easy way. Littlefoot stops her, she insults his mom, fight ensues and they roll down the mountain into the valley. After the fight Cera storms off down the valley, while Littlefoot starts climbing back up the mountain they just crossed.
Also, to be fair, Cera had no idea that any of those terrors were on her path.
Littlefoot's mother said to go "past the mountains that burn." While this wording could still mean going through them, it could also mean that they would go by them. Littlefoot was going the right way the whole time, and his path was consistently difficult without being life-threatening (most of the time), while Cera's choice seemed easier at first but wound up being far worse overall.
Consider also that Cera's big character flaw is her pride. Even when it's abundantly clear that she's made a mistake, they're likely going the wrong way and that her 'easier' way is in fact much harder, turning back is unthinkable for her because it means admitting that she was wrong.
The Woobie: All of the main cast, except Spike, get to be this at some point in the original. But especially Littlefoot.
Acceptable Target: It seems since the MarzGurl reviews of the sequels, they've become a popular subject of mass ridicule. Regardless, a large fanbase for the sequel films does exist.
Accidental Aesop: "The Great Log Running Game" from the TV series teaches us that if something is difficult, you're stupid to keep working at it. You'll just end up hurting yourself.
Accidental Innuendo: The 14th film Journey of the Brave gives us the song "Hot and Stinky" where the gang covers themselves in stinkweed to get past the sharp teeth.
Awesome Music: Believe it or not, some songs in this series aren't just stomachable, but enjoyable! The touching "No One Has To Be Alone" is a good example. There are several big tearjerkers, most notably "Always There", and at one point Cera's dad gets a rock song.
Said rock song, "Tough" is about the need to persevere no matter what and is pretty much Mr. Threehorn's "I Am" Song.
Broken Base: The confirmation that there will be a fourteenth movie after being "retired" for 8 years. Either you're happy to see the dinos mounting a comeback, or you believe that the series has run it's course, and is attempting to milk the Franchise Zombie of anything left. Or, you're in the third camp that is happy to see Land Before Time returning, but would prefer to see a complete reboot of the franchise.
There's also a camp of people who are upset that the series will continue without Kenneth Mars, voice of Grandpa Longneck, who passed away in 2011 from pancreatic cancer, as well as John Ingle (the narrator and Topsy) who passed away a year later.
Designated Hero: Old One is supposedly a wise leader to be admired, but really comes across as a Jerk Ass who isn't willing to do what it takes to save a dying fellow longneck.
It might be worse than that: it's extremely unlikely that any dinosaur species fed exclusively on eggs, although most small carnivores and omnivores would certainly raid a nest if they could get away with it. Ozzie and Strut could be restricting themselves to eggs as a substitute for actual meat. Their normal prey would mostly be small non-dinosaurian animals like lizards and mammals, but there are plenty of examples of those being sentient.
Ear Worm: "Come on lets go, and runaround run around. What a beautiful feeling, we finally found a peaceful vah-leeee! And everyone's having a good time nowwwww!
Despite being overused a great deal, the versions of "I'm So Happy" are actually pretty catchy.
Most of the songs are pretty catchy!
"Legend of the Lone Dinosaur". All this troper hears is DINOSAUR, something something something, DINOSAUR, in an infinite loop!
Ensemble Dark Horse: Plenty, depending on who you ask. Some of the more common ones include Pterano, Hyp, Mo and Guido.
The Rainbow-Faces are a species of this, which may be due to them being magical aliens.
Probably the most popular two would be the first two major guest character: Chomper (see Breakout Character) and Ali, whom, judging from the narrative at the end of the fourth movie, was apparently intended to be the first guest character to be brought back for another movie (although this never happened, and she only reappeared for the TV series).
Pterano is a favorite among fans as well, thanks to being a Tragic Villain.
Guido from movie 12.
Evil Is Cool: Hyp and Pterano, two of the most enjoyable characters of the series, who each get their own very catchy Villain Song, and turn out to be much more sympathetic than they first seem.
Friendly Fandoms: The fandom seems to be in good terms with the bronies, as well as fans of almost everything dinosaur-related.
Fanfic Fuel: What will happen to the gang of five when they grow up and become adults is a very common theme discussed in the fandom.
Ignore ALL the sequels. They're all results of turning a beloved movie into a Cash Cow Franchise anyway.
Accept the original and the first sequel only. No heart after that.
Accept the movies up to IV and ignore the rest. In The Mysterious Island, they got a new director and started using brighter colors.
Accept the movies up to VII. Films V-VII each have their good points, and interesting guest characters, but VII would be the last film to have no non-conspicuous computer graphics.
Accept the movies up to X. We see Ducky and Spike's relationship get some interesting attention in VIII, we get a reprise of the best song from V in IX, and in X we finally meet Littlefoot's dad. But after this, the movies are more sitcom-like in nature, with multiple gag plots, characters like Cera's dad acting wildly out of character, and more explicit morals than people claim the first 9 sequels have.
Harsher in Hindsight: Journey into the Mists has Grandpa Longneck suffering from a terminal illness, which results in Littlefoot and the others going into the Valley of the Mists beyond the Great Valley in order to find the proper cure for his ailment. Grandpa Longneck was played by Kenneth Mars, who later died from pancreatic cancer in 2011.
Memetic Mutation: The "Phonofoot" meme is an image of Littlefoot with a phonograph over his head while saying "And it flew real low", a sound clip from The Stone of Cold Fire.
Moral Event Horizon: In the climax of The Great Valley Adventure, Ozzie suddenly does this when he tries to kill both Littlefoot and Chomper by throwing them off the wall between the Great Valley and the Mysterious Beyond. Luckily, Chomper's parents come in to "save the day".
Nostalgia Filter: A pretty common reason for why the sequels have a fanbase and official forum.
The Scrappy: Again, it varies from person to person. But in particular, the Yellow Bellies from the final movie, The Wisdom of Friends, are widely hated.
Sequelitis: Possibly the most notorious example. Although they do have their fans.
