A trainwreck in plot and script. This kind of story with angst-filled teenagers and distracted parents who live a meaningless paycheck to paycheck life has been done to absurdity many times for decades(Married with Children, Simpsons, etc.).
It's vulgar, silly and predictable in the areas of sexual themes and gender stereotypes. Same sex relationships are now mandatory for every Hollywood movie, S&M toys including butt plugs are tossed in. Yawn. The fight scenes are Chinese style with overacting. Skip this movie. It's made by same people who made the awful Swiss Army Man.
