I watch them all.
It's not better than the amazing ones (_Strictly Ballroom_, _Shall we dance?_ (Japanese version), but it's completely respectable and pleasingly different in parts.
I am an English teacher and I find some of the ignorance about language in some of these reviews rather upsetting. For example: the "name should scream don't watch. 'How she move.' Since when can movie titles ignore grammar?"
There is nothing inherently incorrect about Caribbean English grammar. It's just not Canadian standard English grammar. Comments about the dialogue seem off to me. I put on the subtitles because I'm a Canadian standard English speaker, so I just AUTOMATICALLY assumed that I would have trouble understanding all of it. It wasn't all that difficult and it gave a distinctly different flavour as the other step movies I have seen were so American.
I loved that this movie was set in Toronto and, in fact, wish it was even more clearly set there. I loved that the heroine was so atypically cast. I enjoyed the stepping routines. I liked the driven Mum character. I felt that many of the issues in the movie were addressed more subtly than is characteristic of dance movies.
In summary, if you tend to like dance movies, then this is a decent one. If you have superiority issues about the grammar of the English standard you grew up speaking, your narrow mind may have difficulty enjoying this movie.
