R.S.V.P. is Hitchcock's Rope meets Scream meets American Psycho...with a touch of Jay and Silent Bob. I was leery about renting this one for the longest time because of Jason Mewes. I knew I couldn't take it seriously, but then I thought "Hey, I won't take it seriously." It turned out to be an average dark comedy. But I was right about Mewes. 30 seconds into his first screen appearance he says "B*tches", makes some sexual references, and pulls out a phat bag of weed. Good ole Jay. I thought maybe he would try to do another character, but I'm sure he was hired to be himself. Along with Mewes, the rest of the cast is quite good, with newcomer Rick Otto impressing me the most. The late Glenn Quinn also deserves mention and I'm sad to see that this will be his last role. Director Mark Anthony Galluzzo showed a lot of promise here and I hope to see future endeavors from him. R.S.V.P. is a decent slasher satire but I felt it was missing something from making it a real keeper. I believe it was the ending that left a bad taste in my mouth. Oh well, it was a decent rental. You could do a lot worse.
