As an action movie Kate is a good movie and certainly worth a watch. That's if your okay with a predictable plot and some exaggerated scenes like a woman beating twenty Yakuza all by herself. It's fast paced and never boring and the acting is more than decent. Mary Elizabeth Winstead gave a convincing performance. As for Woody Harrelson he's more a poster filler as he didn't have that much scenes but the once he was in were of course top. I always liked that actor. The best thing about the movie are the fighting scenes, and there are a lot of those, it's all very well choreographed and executed. Bloody violent as well, and it all looked quite realistic. That alone made me have a nice popcorn movie night. Kate is for the fans of that genre.
