The movie isn't bad. It's a decent story, but I wouldn't have paid to see it.
I have to say I'm a bit impressed by Keri Russell's Irish accent. Not perfect, but not bad for an American. I personally can't do one at all, but hers wasn't bad. A few slips here and there.
The story is pretty good in a lot of ways, but isn't atypical of the kind of storyline they're producing.
I think some people were a little too concerned with the dance aspect, but the acting was terrific. I think Keri Russell is a very professional and believable actress.
There were some technical "mistakes", for example, Luis Miguel singing "La Gloria es Tu", which is Spanish, and the Mambo is Brazilian and really goes more with Brazilian music, which of course would be in Portuguese.
Still, overall, I liked the movie. I give it a 7.
