okay so, 65 spoilers in here - non-spoiler short version: I enjoyed it!

jump scares: yes! geyser! tiny dinos!! lightning strikes!!!

disheveled Adam Driver: very yes!

feathers on the dinos? ehhh, kinda? some of the little guys had proto-feather pins/spines

The kid was excellent, I enjoyed her very much

One of the best Adam Driver vs Dino fight scenes is not even seen directly, just via the scanner he was using to find the dinosaur

also, he and the kid don't speak the same language, and yet -as with children everywhere- one of the first things she picks up is swearing
