Mixed feelings. Trailer looks fine, nothing that made me jump up and down in excitement, though.
I'll give them the shield, it's more likely modelled on Ancient Greek weaponry than Cap.
WW1 is an interesting setting, not as well mapped as WW2 so they'll be able to spring surprises. I do wonder why WW chooses to fight in a human war, one good theory I've seen is that the guy in the military uniform is Ares. Not very familiar with WW, but it makes sense.
I'm hoping we finally get a confident, respected/feared female superhero lead rather than underestimated or oppressed, but as this is a period piece, I'm not sure it'll happen. If anyone could pull that off it would be WW, though.
If you guys end up liking the movie and want to know more about the costumes and art/set design for it, I highly recommend this book.
We got a few copies in that store, so I took one out of the plastic wrap and to have a looksie to see if I wanted to spend money on it or not (I'm big into behind the scenes and costume books), but I think it's definitely worth buying. Hopefully I can get it next paycheck.
