Yeah, I've had the exact same problem when it comes to liking Wonder Woman. I've seen some good portrayals of her (I'm thinking "Golden Perfect" arc), but it's like one step forward two steps back with her characterization. Because she isn't showing grief or anger here, it doesn't feel like she really understands what Booster's feeling and like she's so above it all. I don't even know how the writer even managed to make her unlikeable here, since she even showed "real sympathy" just a couple panels ago.
