There was some chatter around it when people first heard about it, and when it was at the film festival, but honestly, I haven't seen a lot of discussion about the movie itself from anyone who'd seen it, neither in this U2-centric part of the forum, or the more general movie threads in the other part of the forum. I was kind of surprised myself, but I don't think it got anything other than a very small theatrical release, or pay to see/stream it via On Demand or other online forums.
I watched it last month via On Demand and have to say, I was not impressed. I thought it had some good reviews (both the movie and Larry's performance) after the Toronto Film Festival, so I had pretty good expectations for it.
