If someone told me that Big Star: Nothing Can Hurt Me is some kind of dry put-on doc about a fictional ’70s band that never quite made it, I would have said “okay, fine.” They were 100% real, of course, but I’ve never effing heard of these guys. I didn’t hear one or two of their songs and go “meh.” I didn’t like one of their singles but then kind of forgot about them. I’ve flat-out never heard of them. So they were definitely doing something wrong in some way. I would have at least picked up on a fragment of their lore, their sound…something would have registered.
