Yeah, and thats what put LBT in the grave. Even though I was 8 when the first came out, I still loved it, mostly cause I had, and still have aspergers syndrome, and love dinosaurs, therefore I liked it, and liked all the sequels except 13, which was a massive dissapointment, because it completed bombed what was a great series, that could have been ressurected with a new director, but the failure it was was like the Battle of Stalingrad, or Berlin, as, like Germany by that time, Land Before Time was on its last legs, and it was just to much for the series that the directors abandoned it. Seriously, they think that kids can't handle dinosaur violence, thats fricking why kids like dinosaurs, violence. A little blood isn't going to scar a kid for life like a 'nasty' scene in LBT would.
Back on topic, if I was director, I would make it something like this.
Redclaw finds a new way into the Great Valley and sneaks in. He tries to kill the gang, but the adults save them. Unfortunatley, Cera was bitten by by Screech or Thud off screen but survived, but Mr. Threehorn blames Chomper, as no one saw the fast-biters.
Chomper triesto prove he is innocent, but the valley exiles him. Chomper leaves, and encounters an orphaned raptor girl, who tells her about her parent's death at the hands of Redclaw. Chomper remembers his own parents' demise, and has enough of Redclaw.
He tries to convince as many sharpteeth as he can to stand up against Redclaw, and that, if they work together, it will work. Only a few listen, but it is enough to stop Redclaw. The gang tries to find Chomper but are ambushed by Redclaw, Chomper's rallied sharpteeth attack Redclaw and force him off a cliff into a lake, where he drowns like a certain scene in the first.
Chomper convinces the other sharpteeth not to kill his friends, and he goes back to the valley after a celebration, but news makes it to the valley before them of Redclaw's death, and of Chomper's orchestration of it. The raptor girl stays in the valley after Chomper convinces the adults she is nice, and they all live happily ever after.
If something like that came from Universal, then we'd have like 30 sequels of Land Before Time, if only. *Sings if only from 11*.
