Just watched it with my son for the first time in ages. It really holds up.
As a fan of the Lonely Island and all of the SNL Digital Shorts they did, this was exactly what I wanted from this movie.
The cameos were crazy.
It was ok. The character design was good, though it reminded me of the fish monster character from Hellboy.
The love story part was meh for me. I didn't really understand the basis of the attraction.
Michael Shannon was the best part as the bad guy. He's great in everything he does.
Movie was pretty bad, and the plot didn't make any sense!
