Anvil: The Story of Anvil.
Loved it. It's about this 80s metal band that should have been huge, on paper, but since they didn't have management or a big break, it never happened. They were influential on GNR, Slayer, Metallica, etc. They kept on playing and releasing albums though. I thought it would be like a Christopher Guest-style mockumentary with lots of schadenfreude, but it was more about how dedicated they are. Sure, there are some cringing moments where they're like "we're still gonna be rockstars...never give up hope!" They are like 50 years old now...but the rest of it was very heartwarming and sometimes sad because they'd get fucked over by bar owners.
Was gonna see them play tonight, but I feel like shit and it was a $20 cover...so I guess they're doing alright for themselves now, heh.
