The one thing I wasn't sure about was whether or not the bracers caused a shockwave, or if she absorbed the power from Doomsday's blast and then released it by smashing the bracelets together.
Either way? Just got back from seeing it and I'm a very happy puppy. She's powerful, she's smart (outfoxes Bruce at one point) and has some great combat moves and some very well done scenes with Bruce. I would have liked to see her spend more time out of combat with Clark (They don't share any screen time out of costume).
Can't wait to see her...i mean see the movie
... again!
