Apparently, Lila is still living in high school. She is prickly and immature. I will admit that the pranks Glenn played in high school were bad. Very bad. But how many years have passed? It is odd that she turned out successful if she is still carrying so much pain. Successful people learn and grow from such trauma. And let it go.
Glenn was even more unlikeable. He was insulting. At least for a while. That is the pattern in movies like this - there has to be animosity between the leads in the beginning and then it completely disappears. Usually it disappears instantly without much transition. In this case, it went away a little slower but still seemed rush. However, they only have 1-1/2 for the whole story. I also thought the end result didn't make sense in that it was rushed.
The acting was fair. The dialogue was flat. The story depended on a Secret Santa theme which is common. There were no great highs or lows or surprises. Most of the tension revolved around either Lila vs Glenn or the guest dancer with neither being earth shaking.
