All right, here's the deal: if you're easily offended then you might want to stay far, far away from this one. There are some painfully funny moments in the movie, but I probably blushed about as much as I laughed. Actually, I probably blushed MORE than I laughed. And if I wasn't literally blushing on the outside, then I was blushing on the inside. If there is absolutely nothing in this movie that embarrasses you then you simply have no shame. Whether that's a badge of honor or not is in the eye of the beholder I suppose.
I will not deny that I laughed quite a bit, but this is a movie that I simply cannot give a blanket recommendation due to its subject matter. If I were to say, "This movie is hilarious, go check it out!" and some sweet, little old church-going lady heads to the theater and has a heart-attack during one of the graphically explicit sex situations, well, that's just something I don't need on my conscience.
So how raunchy is it? Hmm, try about 100 times worse than The Wedding Crashers. Honestly. My mom would've walked out during the first scene. I feel it's my duty to at least warn you of what to expect.
There is some cleverly intelligent comedy here, but that's what I come to expect from the man (Judd Apatow) who had a hand in both Freaks and Geeks and Undeclared. I'm all for making fun of Michael McDonald; the only man whose hair and beard are white enough to give Kenny Rogers a run for his money. Paul Rudd proclaiming, "If I hear Ya Mo Be There one more time I'll Ya Mo burn this place down," is hilarious, but it's one of those things that the majority of the audience won't appreciate.
And when we see a quick 3-second flashback of Steve Carrell singing along to Cameo's Word Up, I laughed for a good two minutes after the joke was over, whereas most everybody chuckled and then forgot about it.
Strangely enough, despite the raunch, there's an admirable moral to the story. The movie doesn't portray Carrell as some freaky loser just because he's a virgin. He's really portrayed as a likable, admirable character. Sure, he's a little weird. After all, he has a framed Asia poster, "more videogames than an Asian kid," and a toy collection that features the Million Dollar Man's BOSS, but we're never led to believe that there's actually anything wrong with the fact that he's a virgin. As odd as it may seem, there's a bit of an "it's OK to wait" message.
But man, oh man, please be warned that this pushes its R rating about as far as it can go. That was certainly Apatow's intention. According to him, he just let some of the guys (particularly Rogen and Malco) improv and talk the way they normally talk, all in an effort to find lots of new ways to be dirty. If you can handle that or talk that way yourself, then you'll love the movie.
I'm not a big fan of excessive profanity and sex jokes. I find that subtle, clever humor is much more entertaining than about 200 uses of the f-word or fratboy sex discussions. But that's me. Like I said, there are some absolutely hysterical moments here, but you have to ask yourself if they're worth sitting through one of the most vulgar movies you're likely to ever see at the theater. I just don't know how interested most women will be in what's discussed by men while playing poker. Honestly ladies, you might not want to know. If you've ever been curious why some girls think guys are gross, well, this gives you a good idea.
There you go - my humble, honest take on what to expect. Be that your guide. It definitely should not be seen with your Sunday School class, mama, grandmama, any family members of the opposite sex, children of any age, or anybody who is easily offended by excessive profanity or explicit sex discussion. If you'd see it with any of the above then you apparently do not have any concept of what it means to be uncomfortable.

Note: I couldn't force myself to actually write up a constructive review of Prom Night. It just can't be done. Instead, I went through what I thought about while watching the movie.
Things that I thought about while watching Prom Night:
-I'm so tired of those dreams where these elaborate deaths will take place, only for the main character to wake up right before she bites it. Of course, when I say "elaborate deaths", I mean off screen throat slashes or stabs in the stomach. Didn't the whole "it's just a dream" thing get ruined by Dallas? Speaking of which, I wonder if a couple stabs in the gut will cause immediate death.
-The film is only ten minutes into and I can already count the horror clichés on two hands. Not a good sign.
-Even after just meeting the protagonist's boyfriend, I'm convinced he will die. Anybody want to place bets?
-The killer in this movie is a teacher that is obsessed with the main character, Donna. (By the way, does anybody think that "Donna" is a horrible name for a main character in a horror film?) He spends three years in a maximum security prison before breaking out and finds Donna celebrating her high school prom. While there is no accounting for taste, I seriously wonder who would take all that time to stalk somebody as dull as Donna.
-High schools allow proms to take place at hotels and doesn't keep track of the students. Apparently students are perfectly able to buy a hotel room and go in and out as they please. I suppose if this plot point wasn't in place, the movie would be 90 minutes of people being bored out of their mind and randomly biting the dust whenever they go to the bathroom. I suppose the trade-off for their excitement is my utter boredom with everything. I've already played "count the pieces of chewed bubble gum under the seat" and "guess how much money I have in my wallet" and I'm only in the 20 minute mark. How else will I entertain myself?
-Note to self: Don't forget milk and bread on the way home.
-Dear screenwriter: You've used up enough false scares to get through this movie and every other horror remake this year.
-The 1980 version of this film wasn't that good but compared to this remake it was like Citizen Kane, or at least The Godfather. It had Jamie Lee Curtis in one of her many post-Halloween horror flicks and it did have a little "twist" at the end. I miss Jamie Lee. I wish she'd act more.
-Apparently at prom there isn't much dancing going on. Instead the girls get in fights with their boyfriends over where they plan to attend college. I hear all these colleges being brought up by name, and I can't help but wonder who these girls have to cheat off of on the entrance exam to get in.
-The killer must carry a bag of really effective cleaning supplies and wipes up his mess between scenes. That's the only logical explanation for why he could stab somebody to death on the carpet or in the bathroom and by the time somebody goes up to the hotel room, there is no trace of a struggle. (On another side note: This is a very lazy killer. Michael Myers went hunting after his victims. Just saying.)
-It's official: the entire audience in the theater is rooting on the killer. What triggered it? Was it whenever Donna went back up to her hotel room while sirens were going off ordering everybody to exit the building? Was it her constant dreams, and how even after going through something dramatic in said dream she insisted on reenacting her steps to a tee? Or was it Brittany Snow's unconvincing performance? I'll have to say it was all of the above.
-Okay, who had "he dies off screen in the third act"? You win the pot.
-Finally, the movie is over. My friend turns to me and says "Donna wasn't too smart." That's the understatement of the week. Kind of like saying that a tornado is a small gust of wind, or a week long power outage is a slight inconvenience.
-I can't wait to get on Rotten Tomatoes and see if anybody gave this move a favoring review.
-I can't recommend this. I refuse to recommend this. This is as lazy of a horror film as any, and the only way to enjoy its cheese smelling plot is if you are under the influence of at least ten beers. And unfortunately for theater patrons, alcohol isn't served.
Rating: * out of ****
