Dance Scene

The whole movie is a waste of time.

... And since Amy (as the writer of the movie) and Judd (as the director of the movie) didn't know how to end it and give a "sorry" speech to the leading man they chose to use this dance scene that didn't make sense at all with the whole story.

Anyway, the ending couldn't save this horrible movie.

I agree with you totally, OP. I really enjoyed this movie and laughed out loud at several points. I thought Amy and Brie Larson were great together and Bill Hader was a riot, as usual.

But that last scene .... ugh! It knocked a 7.5/10 down to a 5/10 in my book.

The ending definitely took things down a notch, although her not keeping up and the dunk flop are both funny. They needed to find a more interesting angle to wrap this up. The rest of the movie really deserved that.

And don't forget the scene with Marv Albert...pointless; it seemed like an out
take or a DVD extra. The last scene indicates they couldn't bring the film to a point or conclusion.

Really? I thought the dance scene was fine. It showed she put a lot of work in to arranging the dance and practicing the routine. And to obviously get out of her comfort zone. All to impress Aaron. I thought it fit well into the movie.

The previous scene with the "Aaron intervention" was awkward though and totally stuck out and didn't work. I'm surprised they kept it in as it didn't really add anything.

I think it was fine and made sense given their argument earlier where she says sarcastically that he should be dating a cheerleader instead of someone like her, and he retorts that cheerleaders at least try to get people into a good mood, whereas she and her colleagues at the magazine are just criticizing people from afar. So this scene ties back to that quite nicely, with her trying to show that she can make an effort for him and bring out a different side of herself without totally changing who she is - sort of like Danny and Sandy at the end of 'Grease'.
