I went for the first time last October. We were looking forward to our US/IOA trip for years and were really excited about it. There were a few good things that were great to see the first time, but to be honest, I don't think I would return to Universal Studios unless
HHN was going on. Even with HHN I would hesitate.
ET was cool. I really liked it even though it had bad reviews. It was way more realistic than most of the other rides at US. It's great for kids and adults.
HRRR was closed when we went.
Men in Black, Disaster and the shows were just okay for us. Nothing phenomenal.
Mummy was the first thing we went on and we were extremely disappointed. The special effects were extremely fake looking and the ride was not very thrilling. HUGE disappointment for us. This was the ride we looked forward to the most at the studios. We were so happy to have no lines for this. We would have been really mad to wait any length of time for this ride.
Twister was okay. It was worth a visit just to see the tornado effect.
Jaws was almost unbearable thanks to an extremely annoying ditzy guide. Wait until night to ride this. It is much better when you can't see anything.
Jimmy Neutron was too rough and blurry. We didn't care for it.
Shrek was just an average 3D movie with slight physical effects.
The Simpson's ride was good. Very realistic and unusual. This made some of the other stuff worth it.
IOA on the other hand was a lot more enjoyable. Mainly because it was themed and had a lot of scenic things to look at. We loved forbidden journey. There is nothing else like it anywhere. I would return just for that ride. We also liked the Poseidon show, Bilge Rat, Dragon Challenge and Ripsaw Falls. Overall, I just think IOA is put together better. Both parks could use more attractions in my opinion.
