As posted in the Simpsons thread, I just got back from Universal and was able to ride Transformers several times.
1. Theme - A+ - I know there have been complaints on the exterior of the building, but I thought it looked awesome, especially with OP over the entrance. Its hard to describe just how big he is until you see it in person. You can see easily from MiB he that big. The Queue is awesome as well.
2. Staff - A+ - We were on the ride before it left the station and it broke down. So we had to exit and wait until whatever went wrong was fixed. The staff did a great job keeping in character and entertaining the crowd.
3. Ride - A+ - The only negative at all is how similar it is to Spiderman. But even with that, it is an incredible ride. My wife has not seen one Transformer movie but that is was outstanding. The Mummy is my favorite ride at US, but I think Transformers has take that spot. It is easily another home run for Universal. I am not going to dog on Disney, but wow, what Universal has done over the past 5 years vs Disney is amazing.
The only complaint I have is crowd control. We just happen to be walking by as a family (12, 7 and 5 year olds) when they opened up the ride one day and literally got run over. I seriously almost punched several people as they were pushing kids (not just mine but others). I am pretty large man but grab my 5, 7 year old up and was getting pushed around like a rag doll. They really should let guests wait in the outdoor Queue if they want to instead of having a mob just gather outside of it.
The good news, at least when we were there, it was opened everyday for several hours. Also, we went in the single riders one night and was told the wait was 60 mins, but was on it in 20 mins. So if you can try that route, it might save some time.
