Don't know why a few people dislike this so much?
Ok, some scenes are funnier then others - big deal, that's normal in 99% of any collab I 've ever seen on NG. Most of the artwork is good or at least ok, and the jokes are funny - some make you laugh out loud, some make you chuckle, but all of them are fine for me.
Especially "Paint", "Sword" (guess I've seen that one before as a stand-alone flash movie outside of this collab, but I may be wrong), "Freeze" and the hillarious "Fire" are well made!
So, all I can say finally is: Take your time folks, this collab is worth a watch!
