A darker comedy?
Finding a darker comedy would be a challenge.
The reason that I think this film is a dark comedy more than any other genre is due to the laugh out loud moments. It opens with a joke, where you get the punchline as long as you know the title of the movie and some idea of its premise. All of the confessionals and their effect on Ig are mostly funny, but very dark and often tragic. The laughs are generally consistent but seem to follow some truly horrifying occurrences which include rape, the demonic, gore, cancer, drug-overdose, and a large dose of murder. In one moment I'm aghast and in the next I'm laughing almost nervously.
What would seem like a few contrasting tones can actually be seen as one consistent tone, when you see the bigger picture, though. Here's my question; Is there a darker comedy? The closest coming to mind is This Is The End but I'd like to hear some other suggestions.
