The Hangover Part 2 was not quite as good as the first movie, but definitely not as bad as the reviews it has been getting. I thought it was pretty hilarious, but it did have some flaws.
To begin with, I think they tried to stick to the formula of the first one a little too closely. Phil, Stu, Alan and Doug head to Thailand for Stu's wedding but, instead of losing the groom-to-be, they wake up missing Stu's future brother-in-law, Teddy. They spend the rest of the movie retracing their steps from the night before trying to figure out what happened.
