I finally saw it, and I didn't like the random killing of a security guard- really hated that in fact. Killing when warranted, I have no problem with, just a random guard- not cool. If it was a monster or something, but not just a normal security guard earning $15 bucks an hour. WW is better than that. Even Wolverine wouldn't do that. He'd kill a NINJA, but not some random rent-a-cop (he'd just hurt him).
Also, really didn't like the Diana Prince identity. It seems like the writer said "Well people won't be able to like her if she's this millionaire superhero unless she REALLY just wants to be one of us. The viewers have to IDENTIFY with her, so Wonder Woman, has to really just want to have an apartment and home just like a normal single girl- otherwise we'll lose the viewer. So let's write that in."
I thought it was pandering. I lost respect for the character- because, REALLY, she can't eat ice cream and watch TV with her cat in her penthouse loft at Themyscira industries? and I also felt like I was being insulted as a viewer. It was just corny and stupid, and couldn't see what it added to the story. I can see where they were going... Diana Prince can relate to the ordinary person. Diana Prince gets her mail and goes grocery shopping. Diana Prince gets a boyfriend... oh no, will he find out she's really WW? But it seemed stupid. There's no dramatic tension b/c she can drop the identity at any time, it's not her. It's just a "place" where she goes to slum with the normals.
I liked a lot of the rest, however, scrap the Diana Prince identity and wanton murder, and there could have been something salvageable here.
