Honestly I would save your money. It is an awful movie. We thought it would be good because of some of the previews and Seth Rogan but it was not worth the movie at all. It is slow and the jokes are not funny. I was disappointed.
If you want a good laugh you should watch one of Rogan's previous movies. Superbad, Knocked up, 40 year old virgin, even This is the End. You would be wasting your evening watching the 2 funny jokes in The Night Before. Just my 2 cents.
