I'll have to pay more attention to it on a rewatch, because after my initial viewing I thought the score was one of the weakest aspects of the film.
It was fine while I was watching it, but a few hours later I couldn't remember a single track or tune, and that's not something I couldn't say about any of the other Predator movies (and not just because half the tracks in Predators are re-used from the original). Just seemed like "obligatory movie music" with nothing that really stood out.
It's also a shame we didn't get anything whatsoever as far as themes from past movies go, or anything that really felt "Predator-y". Even the tracks that some people have said have subtle hints of Alan Silvestri's score I've listened to over and over and I still can't hear it. I get that it would have probably felt a bit out of place to use the straight-up jungle drums, but even AVPR gave us Wolf's theme that felt very much like a Predator kinda tune while still being original.
So yeah, definitely a little disappointed about that.
