Grant Berridge’s review published on Letterboxd :
Zach Galifianakis is everywhere these days!
My theory is that Seth Rogan's agent was on the phone, talking about Zach's awesome talent, and all the simpering motherfuckers in the waiting room immediately ran off to recruit the unsuspecting chump into their sack-of-shit movies.
This movie is listed in the comedy section of iTunes, and even the title suggests that it might be "kind of funny". It isn't.
One Flew Over the Cuckoo's Nest deals with some of the same issues, but does so with more humour.
This movie is shit balls. Avoid.
