"Dance Flick" is a parody of the movie "Save the Last Dance" by the Wayans family.
Like nowaday's other spoof movies such as "Vampires Suck" or "Epic Movie", this movie is nowhere meant to be original.
It is just meant to entertain the viewers and so it does. There is one hilarious scene involving a stage musical, and a funny parody of the song "Fame". Well yes, there are better comedies, but there are also worse.
This is a movie you can watch, if you want to laugh out loud, but it is nowhere a must-see.
The movie itself has some sex jokes, just as a woman with huge privates (we later see her beatboxing with it - all this is covered).
She makes a reference of "having a huge c**t" but then continues "...ry music collection".
Otherwise, the language is average mild PG-13 language.
Several characters point with guns and so on.
In a film-in-film sequence a man hacks off his leg (obviously fake, some tissue is seen - Note this is a film-in-film).
Like with the movie "Save the Last Dance", the main spoof, there is the question if a relationship between black and white people is okay - however this movie makes fun of it.
The jokes don't seem too offensive, since nearly everyone involved is colored.
After all, this is suitable for viewers 12 and up.
