After seeing the new figures based on the Justice League characters appearing on the show this season though, my resolve dissolved, and I snatched them up with the help of a friend locally.
These guys look just like they do in the show, which is impressive considering this is a mass market retail line. The following pictures are of Flash, Superman, Green Lantern, Hawkman and Martian Manhunter.
Now, these aren't Marvel Legends level articlated, or even DC Superheroes/DC Universe Classics level, but they are pretty good for about 5" figures. They have neck swivel, shoulder, hinged elbows, waist, T-crotch and hinged knees. The paint applications on mine are all pretty good as well. Flash has a few little white marks here and there, but for mass market they look good. If you have the chance to look over a few of each (which with their being 1 per case is unlikely), you may find a good one.
From what I've seen Lantern and Hawkman are in one wave, and the other 3 are in another wave. There is also a 2 pack with Batman in some crazy armor with a Superman with Kryptonite veins on his neck and chest. If you customize at all, that might be a better bet for your Superman fix.
So in my opinion, if you're a fan of the show, or even of the characters themselves, I'd think about getting these figures, if you can find them.
