Just after watching the documentary "Drunk Stoned Stupid Dead" I discovered that there was also a TV movie covering the same period, focused on co-founder Doug Kenney. So I had to watch that, even though the reviewers were middling.
I don't understand those middling reviews, because I thought this was tremendously entertaining. It's basically a movie about very witty people saying funny things, held together by the protagonist's downward spiral. It is less reverential than the documentary, which tiptoed around the whole priveleged-white-male thing, and it does it's best to mock itself, as when a scroll points out all the discrepancies between the movie and the real story.
The movie does at times rely too heavily on its narrative devices, sometimes falling into a gimmicky cutesiness, and the ending feels like a flailing attempt to pull things together, but overall this is funny and very well acted. My advice: ignore the critics, watch the movie.
