I am BIG fan of Justice League and Justice League Unlimited. There, I said it.
The above is titled A Better World. This episode worked very well due to the Justice League team running into their inter-dimensional doppelgangers. Seeing the different sides of the doing the right thing and going completely bat guano over the top. This episode has everything, even Doomsday! Doomsday makes everything better!
So sit back, ease into your Friday with some super heroes kicking the crap out of each other.
