I love the acts by the various acrobats, but hated the ringmaster and Dorothy because they were annoying as hell. I think they over did it with all the F-bombs and stupid jokes.
The various acts were interesting and some were quite breathe taking. I'm not sure if I'd come back again though.
Regarding seats, there's no real bad seats, but I do recommend you sit up in the first row. You'll get picked on and what not and it's funny.
