Yessss, I miss Jimmy Neutron! I only rode Despicable Me once during EE to see what the deal is and because it was a low wait time. I was disappointed. It gave nothing new, except for having to wait in two separate pre-show rooms. I mean, really? Also, is it just me, or does the theater seem smaller?
However, I have to admit, it's all about personal preference for characters really. I'm sure if I actually cared about Despicable Me it would be different, but I could careless about the franchise. Jimmy Neutron was something I grew up with, so obviously I would be biased.
I liked the movie, but not into the ride. Jimmy Neutron was just a fun ride. We always got a kick at the end with the chicken dance song and "llama llama llama".
