People be giving less stars because as they claim the acting was bad. Everyone really tries so hard to play it expert when it comes to movies. Just sit down and watch the movie. It wasn't a perfect movie but it was definitely enjoyable and not half as bad acting as the majority of all new movies. Definitely has some flaws but you can't have everything in life. Don't hesitate and go watch that movie. It's really good
