I did mention the noseguard... I mentioned that I hated it. ^_^ Yes, I see why it's there, to make it look more warrior-like and all, but the plain fact is I think it looks dumb. If Wonder Woman (I'm not on a first-name basis with her, so I won't call her Diana ^_^) had been wearing an actual Greek helmet, or just a helmet, then the noseguard would have been perfectly sensible... but she's wearing a tiara. I'm sorry, but a noseguard does not belong on a tiara.
And a lot of people have mentioned the "comedy/parody" possibility, but I think that even if it is a subtle parody (and I actually don't think highly enough of Frank Miller to find it plausible that he could be that subtle), it's still pure garbage. Just because something is a parody doesn't automatically make it good... otherwise Epic Movie would have been brilliant. ^_^
