Jurassic Park was my favorite ride at Universal Studios Hollywood, and I would base decisions on going purely if it was open or not. When I watched videos of Jurassic World, I was really disappointed with the screens and the lack of stuff in Predator Cove. However, I have now gotten a chance to ride it 5 times and I love it. It isn't perfect and there are some things that I prefer about Jurassic Park, but this is definitely my favorite ride in the park and one of my favorites in all of California.
The aquarium scene does look way better in person. However, I greatly prefer the original beginning since it wasn't a series of screens. I can forgive this part though since I love most of the rest of the ride. Once I got to the first AA Dinos, I was amazed at how good they looked. I know these are just reskinned old dinos, but they look like new and it greatly improves the experience. Predator Cove works way better in person. There is a lot of atmosphere in the area that you don't get from watching videos. I think it does a great job in building up the tension for the finale. However, I would like to see some stuff added to this area. Something like the falling jeep scene, plus a couple of smaller dino AAs would make this perfect.
I actually didn't mind the use of screens up the lifthill. From the moment that the raptor drops out of the ceiling until the end of the final drop, this ride is amongst the greatest of all time theme park experiences. The jungle setting, Blue, the Indo plus the old dinos including the T-Rex all make me absolutely love this part of the ride. It more than makes up for the weak start with the aquarium. I am excited to see what the Indo will be like once it is in A mode.
