The camera work is entertaining, especially, oddly the closeup scenes of shoes being manufactured, streams of colour zipping along to the upbeat music.
It is a movie without villains. The conflict comes from selfish vs unselfish motives, self direction vs worrying what others think, despair vs taking responsibility.
Of course the theme of tolerance for diversity is woven through. The movie does not have the usual silly Hollywood tolerance breakthroughs. It comes in fits and starts with back pedaling and tolerance from surprising sources.
The lead drag queen Lola sings better than anyone on American Idol, in a genre all her own. The musical numbers are far better than you will see an any real world drag show. These are not female impersonators. None of the drag queens would ever pass as female.
This is a character-based tragi-comedy about wildly different outcasts interacting. Of course the basic plot is predictable if you watch the trailers and use your intellect. But that is not how to watch this comedy. It is a bit like complaining that Lucille Ball was inevitably going to get herself covered in some sort of mess in the Long Trailer or that a Marx brothers comedy would end in a pie fight. Immerse yourself in the movie's reality. I was genuinely surprised by the ending, though in retrospect it was inevitable. Plot twists like a murder mystery is not what this movie is about. If all you care about is plot, skip this movie; it will go over your head.
All said, unless you have a heart of stone, you will come out smiling and more optimistic than when you went in.
