Look, this is straightforward. Go watch the trailer. It's an honest trailer, it shows what the movie is generally about and shows the kind of action you can expect. If it appeals to you, then you'll probably like the movie. If it appalls to you, save your time and money.
It's pretty weird, light entertainment. Because it's about such touchy subjects (slavery primarily, though there are other raw nerves a-plenty here) it has generated some controversy. Well, people will always try to read baggage into where there is none. If you can get past that, it's a fun watch. Doubly so if you can manage to smuggle a flask of whiskey into the theater on a loopy Friday evening after a rough week at work.
Bottom line: 3/4 stars if the trailer appeals, 0/4 stars if the trailer appalls. Pick your poison.
