Strangely, I kind of like the outfit. I'm not sure why. I think it's because different people will key on different items as essential to the character's look.
For instance, if I had to boil down the Batman outfit to it's basic component, I would say the pointy ears on the mask, the fringed cape, and the bat inside a yellow oval on the chest.
For me, Wonder Woman's costume need the strapless bustier with either has a gold eagle or two W's that look kind of like an eagle, the headband/tiara thing, and the bracelets. Everything else is optional. I don't mind the long pants or the blue boots. I think the look works. I think it works better than the new look in the comics.
Strangely, the new comics costume is similar to the TV show one, except the colors are all darker because badasses always wear black. Morons. And there's that idiotic jacket thing. I don't know. I just prefer the TV show costume at this point.
As for the show's description, I remain hesitant. Being a TV show they probably can't do the big budget stunts and special effects. Hopefully there will be some decent super heroin' action. But that it will be light-hearted comedy has me worried. If they have some good writers who actually understand that comedy is not just lame one-liners, then it might work. But it might also be painful to watch if the writing is bad and writing bad comedy is exceptionally easy.
The direction they've chosen could work and may become a hit if enough people tune in and the writing is sharp enough. But it's a direction that smacks of laziness because only fools think comedy is easy. I'll watch the pilot but if it fails to work, then it's unlikely to pull itself together long enough to find an audience.
