Well we know the premise of this movie basically from the title. Dick dies and only his two best friends and band mates know how it happened, only thing is, they're not talking.
I have to admit, I did NOT see that twist coming due to how suspenseful and shrouded in mystery of Dick's death was throughout the majority of this film. Chances are you won't see it either. So just do your best to imagine how 3 low IQ, bumbling, no talent, drunk, high, rednecks act up to when they're left alone to their wild shenanigans.
This movie isn't a "comedy" in the sense that there are jokes or any sorts of punchlines. The characters themselves ARE the punchline to a really bad and tasteless joke. There's no slapstick or outright humor to be found, yet it's comedic aspect comes from just how clueless the main character is and how every decision he makes just makes things worse for himself.
So it's a weird movie and it's pacing definitely won't be for everyone. I rated it a 6 because while it kept me interested and curious the entire film by the end of it I wished it had gone further with the content. It's equal parts mystery, suspense, and comedy with an answer to a question you just plain aren't expecting but at a relatively slow pace. There's no gag or gross out humor, no nudity, just some occasional swearing.
