Also, now I've watched it, I can now give my proper thoughts!
My only exposure to jimmy neutron's nicktoon blast is through youtube, but I know I love it and I have a general idea of what it felt like due to minion mayhem. The chicken dance must have really rocked people around!
I love the queue and post show footage, as that is surprisingly rare for such a newer ride. Guest universal must have been strict there. But videos of the ride itself aren't too hard to find. If you want a total nostalgia trip, seek it out.
The idea of rotating nick cartoons is really interesting, but wouldn't have worked due to nick eventually killing most nicktoons and only repeating spongebob. I guess in an alternate universe where nicktoon blast lasted, it might have become nickelodeon blast and would have included the sitcoms, such as icarly.
