I'm not really loving either of these, but I'm hopeful that Superman's costume will look better when we see it full in better lighting and that Catwoman's costume may be just a prototype. My biggest annoyance with the Superman costume is probably the S symbol. Although, it's an awkward angle, it does look weird. Would it be asking for so much for them to do a symbol like this? (Ignore the rest of the costume and just focus on the S, people.)

As for Catwoman, I don't think they have to worry about reminding people about Halle Berry's Catwoman with this look. That's something. I'm hoping that if her costume does evolve into something more Catwoman-like, it will look sort of like the design from the upcoming video game Batman: Arkham City. It has a realistic and practical look that still feels like the character.
