Unholy: An Ethical Decision.

I have an ethical decision I need to make and could use a little help. A good friend of mine from college directed a movie that I told him I'd review on thoughtsonfilm.com. Here's the thing, though my buddy did a good job on his end of things, (well edited, reasonably well acted, reasonably good bang for the buck, and over all, I'd say its got an excellent visual style) at the end of the day the movie pretty much sucks. Its convulated, the dialogue is lousy and to be frank the whole thing is extremely limited by its budget. And the ending is a twist of Shaylamalomian porportions in both disappointment and retardedness. So what do I do? Honest review? Pandering?
