The game focuses more on the unique artistic segments achieved by the simplistic 2D art style combined with the semi-realism of the 3D backgrounds so there's not much in the way of "story" however the game is short enough that if you're only interested in that aspect you don't have to wait very long between the segments that are more character focused.
The characters are all pretty funny and interesting (Especially Benny, I <3 Benny) and although you'll have to play the game multiple times to see everything it's short so it's not too hard to get through again even though you'll be seeing a lot of the same content again.
