This is a weird thread idea I've had for a while, it probably won't work out, but…
Take two things that are sort of similar, but so different that they normally wouldn't invite comparison, and compare them, to try and determine which is better.
For example, compare Cats Don't Dance with Big 0.
One is a western animated movie, one is an anime. One has Scott Bakula as a tapdancing musical cat, the other has Steven Blum as a psuedo-Bruce Wayne that pilots a giant robot. One has a an evil version of Shirley Temple, the other has a girl with a cd drive in her head. One has a giant gorilla manservant with a booming voice, the other has a butler that carries around a semi-automatic rifle. One has glitzy musical song and dance numbers, the other has giant robot battles. Both have an awesome soundtrack.
Which is better?
Okay, mostly I've just been wanting to get people to compare Cats Don't Dance and Big-0 because they're so different. But I thought as a thread idea it could lead to other interesting stuff.
