Oh man, every time someone asks a question along these lines I always think of the movie Hank and Mike. I found it in a discount bin at a grocery store probably a decade ago so I took a little time to actually look into it more this time. I knew it was Canadian and unlikely a big hit, but apparently it was just so poorly received. It made less than $17,000 of the $2M it cost, and it's real tough to find anyone even reviewing it. I even struggled to find the music from it. (The one song is badass). And it's got a couple B-tier actors that I remember doing a great job, and I think Joe Mantegna really went for it in his role as the god Pan. Chris Klein kills it in this song.
The crude humor kinda puts people off I think but the satirical aspects cut a little deeper than the movie needed to. And probably when I discovered it I was depressed and had a drinking problem and the overall mood of it really felt at home to me at the time so I was able to just live in those aspects of the film and really absorb the more subtle message. It's definitely absurd in many points but there's a lot of heart in it.
