boring
I gotta say it -- I find her acting rather boring and flat. She's quite pretty and is rather a chameleon (can look very different in different parts), but I have yet to be pulled in by her in anything I've seen her in.
I thought American Sniper was very good and B. Cooper excellent, but I thought her portrayal of his wife was a weak point in the film. Sure, she held her head in anguish and shed a few tears, but I just didn't see any real understanding of complex emotions coming from her. So I'm still unimpressed by her and fail to see why she continues to get highly visible parts like this.
(I know, I know -- I'm bracing for the the vitriol of those who disagree!)
