I haven't seen the movie but I also heard that it's brutal.
Here's the first paragraph of Roger Ebert's review (he gave it 3 stars) which will give you a good idea of what to expect.
Speaking of movies that go over the top, "Running Scared" goes so far over the top, it circumnavigates the top and doubles back on itself; it's the Mobius Strip of over-the-topness. I am in awe. It throws in everything but the kitchen sink. Then it throws in the kitchen sink, too, and the combo washer-dryer in the laundry room, while the hero and his wife are having sex on top of it.
This sounds too good to miss.
