I'm pretty confident that I've spent more time discussing this one specific sharptooth with people on the wiki than I have characters like Bron, Tria or Ali. Make of that what you will.
Speaking as someone who has spent 70% of his time buried in the sharptooth aspect of the series over things like stories and actual characters, and as someone who is decently fresh off of all fourteen of the movies, I think it's inoffensive as far as sharpteeth go; it is lame, but at least it does more than just stand around and roar and trip over tiny pebbles like some of the later ones - heck, I don't even think it's the worst in its own movie, I would argue that that honor goes to the random T. rex that pops up at a point during the climax.
Oh yeah, you and I had a lot of discussions about that guy (and the other sharpteeth too) on the wiki from 2017-2019, that’s for sure...
Given that Allosaurus is my favorite dinosaur, I was hoping that they would have done something to make it more scary. The only thing impressive about it was the fact it survived that fall...
At least the music tracks accompanying the scenes in which it appeared were dramatic enough: Sharptooth and the Earthquake, of course, and also that one theme from the original where Littlefoot saves his friends at the Mountains That Burn. I think that played twice; first time was the Michael Tavera remix and then the original Horner version.
But despite that, the music doesn’t completely save the Allosaurus. However, I do have fond childhood memories of watching VI on DVD, seeing it on top of the log, slowly moving towards the stuck Spike; that is a scene that is embedded in my head forever, for some reason. Was it useless? No, it served a purpose in the plot. Littlefoot probably wouldn’t have been able to attempt to “fix” the “bad luck” without it falling to its apparent death. What else was he going to do - go look that random T. rex that was out there?
