BE AWARE THIS REVIEW CONTAINS SPOILERS
Although many are killed in this movie, it isn't very gruesome because they mostly get burned up by the sun. However, one guy commits suicide by slicing his wrists (off screen), and that is kind of bloody, and there is this one guy who got burned up by the sun. However, the burned up guy is not that gruesome. If you have seen the burned up Anakin from Star Wars 3, than it won't be that shocking, except for the fact that his arm is ripped off. Besides these and the occansionaly blood, violence isn't that bad. F--k is said a lot in the film, along with s--t and b---h.
