Here is a recap of the past Scary Movie films and what I thought about each of them:

1) Scary Movie (B-)

2) Scary Movie 2 (B)

3) Scary Movie 3 (C-)

I can say that it is official: the Scary Movie movies have ran out of juice.  Scary Movie 4 is the the worst Scary Movie out of all 4.  I think we can all remember when Scary Movie was actually funny, you know the ones that have the Wayans brothers involved in it.  Scary Movie 4 spoofs many films such as Saw, The Grudge, Brokeback Mountain, War of the Worlds, The Village, Million Dollar Baby, and much more.  To my surprise, they didn't spoof as much movies as they did the other films.  Of course, Scary Movie 4 continues the life of Cindy Campbell (Anna Faris) and her very bizzare life.  That's all the story, you should know if you watched the other movies.  She falls for Tom Ryan (Craig Bierko), who of course is really Tom Cruise.  You want to know one thing: there were probably hundreds of jokes in this movie, and I only laughed three times total, yes I remember.  I was so bored in the theatre, this film had joke after joke, and almost all of them were lame, and most importantly unfunny.  I'm sorry, some of the jokes even went on for too long of a time, even when they started out unfunny.  You want to know the tradgic part, I saw many talented actors waste their time and get humiliated in Scary Movie 4.  A couple of examples include Charlie Sheen talking a whole bottle of Viagra pills and washing it down with vodka, James Earl Jones getting run over by a bus, Leslie Neilsen getting his clothes zapped (and we get the pleasure of looking at his rear end), Bill Pullman getting his nuts wacked by Carmen Electra, and last but not least, great actress Cloris Leachman getting bathed in her own pee by Anna Faris.  Wow, just wow, I think the reputation of all these fine actors were burned after Scary Movie 4.  I'm sorry, but that Brokeback Mountain joke was probably the lamest joke ever, everyone needs to stop saying that was funny because it wasn't.  The Million Dollar Baby joke was also very, very, very lame.  In fact, that's the word to describe this crap movie: lame.  I mean, I laughed three times, that is not even close to good.  You know,  I actually had a better time at Date Movie then I did at Scary Movie 4.  I had no fun whatsoever at Scary Movie 4, in fact, I really wanted to walk out of this movie.  Scary Movie 4 felt lame, generic, unfunny, and very unsatisfying.  I would give Scary Movie 4 a D.
