It is a musical. If musicals are not your thing, then this might not be your thing.
That being said, it is a happy and refreshing movie. There is some language and innuendo, that maybe was not necessary but it is PG13 - so you know. Great musical numbers and dancing. Like that they kept special effects to strictly necessary and favored a more stage/theatrical approach - especially on the dance numbers. Some are big ensemble numbers that gives a nod to Broadway and West End as the movie takes place in NYC and London.
The movie also frowns upon social media bullying - a kid seems to commit suicide as a result which is something that does happen. Some people will take issue on that - I appreciate the bold move.
Pleasantly surprised on how they reimagined the Christmas Carol to make it different yet relatable.
The soundtrack is excellent.
