If you have any kind of sense of humor, you will love this movie. If you haven't seen it, don't even bother renting it. Just go ahead and buy it.
The only problem is that the Blu Ray disc won't play on all PS3s. My boyfriend and I both have PS3 Slims; his a newer model, and mine is an older one that I bought refurbished. One of us has more GB than the other, but I forget which is which and I'm not sure that's even related. For whatever reason, mine will play the Blu Ray and his won't. If the Playstation 3 is your only source for a Blu Ray player, you might want to get the DVD instead. Or, better yet, just go ahead and buy a cheap Blu Ray player because there are a lot of discs that won't play on a PS3 for some reason.
