Rented it the other day and didn't like it that much.
I found it hard to believe the characters as a group hanging out and the banter between them wasn't quick, crisp and witty like the characters were in Superbad.
The plot had potential but it came off super cheesy to me and I don't care if they planned it that way or not. It didn't work for me. I did like the soundtrack and it sure brought back a lot of memories
The Hangover was much, much better.
I'd say HTTM is worth a rent if you can't find anything else on the shelf.
