When Ally finds out that she's been nominated for 3 Grammys and that she's booked SNL, as well as during her acceptance speech at the Grammys, Gaga's reactions rang false to me. For most of the movie, I was very impressed by her very natural characterization, but in those moments, I could see her acting. Perhaps it's because those things actually happened to her, so it was difficult for her to act naturally, but it came across cheesy to me.
