The movie was OK for me, without Lady Gaga the movie would even be "average" and wouldn't have so many media attention / visitors I guess.
Her performance is definitely outstanding and her voice can be quite powerful as could have been heard previously on her Tony Bennett collaboration. Probably the story should have been a little bit more elaborated, then I could have been a "movie of the year" candidate.
The shots are nicely done, even the "long" shots seem not boring. I liked the "on stage" feeling you have with the sound that was nicely done. But I didn't like all these thousands lens flare during the movie.
I'm glad I've seen the movie but it wasn't a memorable one.
