Among the music documentaries now streaming at Netflix is the 2010 film "Lemmy." If you didn't know Lemmy — who died last Decemmber — he was the iconic leader of prototypical ampheto-metal act Motörhead, a former member of astral-rockers Hawkwind, a military history buff/collector and, when not on tour, a daily sit-at-the-end-of-the-bar/Jack-and-Coke/video-poker-enthusiast at the Rainbow Room on L.A.'s Sunset Strip. Well, Motörhead was indeed a pretty great and influential band, and there is no shortage of famous musicians interviewed here attesting to that fact and that Lemmy was a nice guy and quite a character. It's a bit odd when he laughs about abandoning one of his sons while his other son chuckles along with the gruffly inflected anecdote but ... It's all interesting, even if you're not a fan, but that but doesn't change that Lemmy is not remotely a compelling interview subject or that, over the course of almost two hours, the viewer doesn't learn much about any creative well spring that fueled his art.
