It wasn't screened in advance for major critics. Not that I can judge the film (which I haven't seen, and may not see at all, period), but I can't say I'm too surprised by the studio's decision there.
That's not a good sign. Once in a while it just means the studio is completely clueless as to what kind of movie they have (Tombstone), but almost always we're talking about Snakes on a Plane, Disaster Movie, Saw XVIII, Street Fighter: The Legend of Chun-Li and BloodRayne. Even a bad review lets people know about the movie.
