Decent watch, probably won't watch again, but can recommend.
This is sort of a poor man's "The Hangover", or maybe just a standard bachelor party trope. There are some fine twists along the way, but the way it plays out, it tries to do 2 things and sort of fumbles both.
It fails at being a bachelor party style movie as they have a limited amount of actual fun during all the abuse humor, and the only woman I was excited to see was Jaime Less Pressly, playing herself.
The other thing it tries to do fails as it hampered by the sticking to the bachelor party format when it would have been much better to go completely off the rails.
It's fun, it's funny, but any of the Hangovers or the American Pie movies are probably going to be a better watch.
