Saw this with the missus yesterday.
Acting was generally solid, although there were a couple of spots where I could see Gaga acting (hope that's clear). Her voice, as always - tremendous and Bradley had a surprisingly good one. Sam Elliot - as always - rock solid.
This just didn't hook me. I think I've seen it too many times making me almost inoculated to the pain. You know exactly what's going to happen because it - well happened it the two earlier versions. Also didn't care for the fact that Ally (Gaga's character) had almost no spine when it came with dealing with her agent - seemed counter to the otherwise string character they were developing.
Eye candy for my wife = A (she loves looking at Bradley)
Overall movie = B -.
Worth the price of admission.
