There were some similarities, yes. Plenty of the movie sounded like Predator (as did Predators), but the more "original" sections sounded very much out of place - as though they were influenced by Silvestri or Williams scores. Particularly the brassy motifs that generally aired during "triumphant" scenes, those sounded similar to Silvestris motifs in Back to the Future. Several parts also sounded similar to Williams when villains appear on screen (the original Star Wars trilogy.) Like I said, it could've been the fault of studio temp scoring, but to me it didn't quite fit.
