As anyone who has taken too much alcohol can confirm the stories you tell the day after are much more interesting than actually being on the party - and that's why it is also funnier to see this comedic story being revealed step by step than getting everything shown at once in the face. Everything that happens in Las Vegas stay in Vegas, but this crazy party deserved to be told to the masses as it contain everything.
The best part is that - even without toilet humor and controversy - it manages to be somewhat funny. And that is probably because of three leads that could turn every situation into humor thanks to their unique personality. Other than that, it's nowhere near its reputation - a few laughable moments are not enough to turn this into franchise. I would took "Very Bad Things" any day over this.
