It's true that there may be moments in which the evolution of the story gets stuck but Christopher Lloyd's surprising work and the great chemistry established between him and O'Brien makes it worth watching it. [Full review in Spanish]
The idea of witnessing a killing spree from the p.o.v. of a town's funeral home is full of rich discomfort. It's the stuff of the sub-subgenre itself that gives you a boregasm.
A uniquely wry tone sets the film apart. I Am Not A Serial Killer is unmistakably a drama, but it's a strangely cheerful one given its dark subject matter.
