The story follows a dopey dude into an unbelievable conspiracy and ends with a most unlikely conclusion for an American film.
Lots of laughs and also lots of codes, which may or may not reveal the identity of The Dog Killer if you look further into the film online
If you liked "Inherent Vice" or Coen brothers' comedies like "The Big Lebowski," although this one draws more heavily on Hitchcock's "Vertigo" and "Rear Window" than the brothers' Raymond Chandler influence.
It's got a heap of adult-oriented material though, so not suitable for a general audience.
