Unlike targeting genre defining films (Scary Movie vs Scream), horror classics (Scary movie 2 opening vs The Exorcist) or interesting debuts (Scary Movie 3 Vs Ring/8 Mile), Scary Movie 4 targets films that, while they may have done OK at the box office, not a lot of people are interested in. Not to say those films are good or bad, they're just not interesting enough to draw the laughs. In fact, the only real laughs I found in this film were the Brokeback Mountain parody (Mostly because of Anthony Anderson) and the suicide bomber joke (and that only really drew a laugh because it was so un-expected and so un-pc).

Cast wise it's the usual suspects. Charlie Sheen turns up for a brief cameo, taking the pastiche out of his bad boy, sex maniac persona, and there's an interesting turn by Bill Pullman, who is always better in a gentler comedy role (see Casper). Anna Faris pops up again as Cindy, and although she plays the character well, the character herself is becoming increasingly irritating and generally dislikeable.

If these movies are to continue (and why shouldn't they, after all they make a mint at the box office), then they need to rethink the scripts and find a new lead character. Mind you, I suppose it's still better than the romantic comedies being released!!
