It's loud!
If you love STOMP, you'll love this (most likely).
If you didn't love STOMP, then you'll probably want to pass on this. It's entertaining enough but not my first choice for entertainment.
The guys are cute and they seem nice and talented. It's not exactly like STOMP because it's a bit more comedic, but I'd put the two in the same genre and it's not really my cup of tea.
