Almost every AA in River adventure is outdated. I think the only ones that are good are the stegosauruses, the Dilophasauruses, and the T-rex. The effect where you are supposed to feel stalked by raptors in the bushes doesn't have enough foliage so it just feels like machines moving branches. Universal has shown it has FANTASTIC AA technology with the raptor encounter, and it's extremely clear how outdated RA's AAs are when compared to RE. The scene where you enter the raptor area feels too calm and staged, there are only two really terrible AAs chewing on a shirt.
Love the ride, but it needs an update more than any other attraction at UOR IMO. Except maybe Ripsaw. Except maybe CitH. Except maybe E.T. Exce-
