Grimm Love is not a horror film, per say, but the subject matter could be downright unsettling to many people.
While the official plot description of the film states that an American student becomes obsessed about a case of cannibalism she is doing a thesis paper on in Germany, the real story is focused on the two men involved in the aforementioned human dining experience. One wishes to eat someone and the other wishes to be eaten by someone in a very unpleasant manner.
There is a long lead-up as the film plods on at a snail's pace as the student explains to us the tragic backgrounds of the two men. However, once you realize what exactly is to occur when the two men meet, you begin to wonder how far they'll go on-screen. It's not a graphic film when compared to many recent movies that leave nothing to the imagination, but it is nicely done to leave the viewers squirming in their seats...particularly the male viewers.
If you are looking for an action-packed bloodbath, this isn't the film for you. If you are in the mood for a deep psychological film with a literal bloodbath, this is one for the must-see list.
