This is almost identical to "Scary Movie", but seven stars worse. I got no laughs out of this. I watched this because it is a parody film, and Simon Rex was in it. I only liked Simon Rex in it. The rest of the actors and actresses were bad and the movie worse than them. If you wanted to see a "Friday The 13th" parody, don't watch this, even though it's title is "Shriek If You Know What I Did Last Friday The 13th", it has nothing to do with the movie. And, of course, when I ordered this, they sent me two copies, so if anyone wants a bad movie, let me know.Rated R. I do not recommend for 15 or under. Strong sexual content,language (but not a lot of the f word), parody violence, and some other stuff.Bad movie. Don't watch.

I am happy to say that I came into this movie with high hopes, and I was not disappointed. First off, this isn't a rip off of Scary Movie, since they both were made at about the same time, and personally, I think it's better! Despite having a FAR lower budget than Scary Movie, this film managed to work in a few stars and quite a bit of sight gags (i.e a cigarette machine in school and some coffins coming out of woodshop). I read the reviews before watching the movie that I had rented, and I was a bit worried, but I quickly forgot and began to watch. I was laughing within the first two minutes when the killer falls into her swimming pool. The opening is by far the funniest part of the movie in my opinion, although the fourteen second musical number "Grease Frightening" is pretty hilarious, especially afterwards when the killer chases Slab with Christine. Although the jokes are over the top and silly, they worked perfectly and the entire movie was hilarious. However, the end scene bugged me as it wasn't as funny as the rest of the film and felt sort of rushed. The point is, if you loved Airplane! and the Naked Gun movies, this film is for you. There was hardly a dull moment, and all of the sight gags and jokes provided for long fits of laughter. Here's one of my favorite quotes from the film: -After all, tomorrow is Halloween.... -AND Friday THE 13TH!

guys, first see scary movie and compare it with shriek if you........ yes, i am too lazy to write its title, but that's not why i didn't like it. this movie is childish. the jokes were hackneyed, and nothing fresh was seen. this film is basically a spoof of "i know what you did last summer" and some other horror movies. and long story short, it was lame. it was no match to the "Scary Movie" trilogy. the funniest part of this film was...........oh yeah there were no funny parts. terrible and an absolute waste of money. i should have taken a nice nap instead.2.8/10

my personal feeling is that this movie is better than any of the Scary Movie Films.i found it more relevant and clever.it is better paced,with no real spots that lag.the jokes do fly literally about every few seconds.i woudn't say it is funny,but there are some very amusing moments.i particularly liked the end stages of the film.to me,this film is lighter in tone than the Scary Movie franchise.it's also not as gross.the violence is also less graphic,and the language is much tamer.there is very little in the way of nudity,and most of the sexual situations are implied.the movie is rated R,but i'm not sure why.after watching it,i thought it would be PG-13,at most.i checked the rating after watching,and i'm really surprised.from my viewpoint, i think this movie would be suitable for most kids 13 or older,but parents should use their discretion,of course.either way,i thought this movie was pretty entertaining all the way through.it's no masterpiece,but i give this movie a 6/10
