Why?

You know, as excited as I am about the new lego Batman game, being that I enjoy legos period, and the games combine the best part with having legos without the irritation of finding a storage place or losing them, I've never quite understood the point of lego-themed cartoons.

Isn't the point of lego Batman or lego Star Wars to represent the characters/settings/situations and have fun play-acting them? And/or using the pieces to build bizarre and amusing things?

I've never seen the Lego Star Wars cartoon stuff, so maybe there is some weird appeal to them. It still strikes me as very strange however.
