My son talked me into watching that movie. It was gross, weird and very interesting. The acting was first rate, the plot was strong and the writing and directing were tight. The guy I'd taken my son to see as Harry Potter when he was growing up was now a talking dead guy, but he pulled it off. Dano was great in his despair, horror and aggravation at the corpse that wouldn't shut up.
I ended up recommending the movie to a coworker who has similar tastes to my son. If you like weird, funny and a little gross, you will probably like this movie.
