I think it's really fun. It was worth my $50
It just depends on what you like. The cartoonish animations and the weird quirky sounds are kinda cool, and pretty amusing. The campaign is kinda short, and the Online is pretty chaotic, but in a good way. No Voice chat makes it difficult to communicate with your partner during co-op, but they implimented some game controls to help with it (but i would much rather have voice chat and a headset)
Rent it. thats the best piece of advice i can give you since i don't know what kinda of gamer you are.
