At the time I came along Hollywood's idea of teen movies meant there had to be a lot of nudity usually involving boys in pursuit of sex and pretty gross overall. Either that or a horror movie. And the last thing Hollywood wanted in their teen movies was teenagers!
There's no such thing as an actor giving positive criticism to a director. The minute you say 'Don't you think it would look nicer...' that director's going to hate your guts. Particularly if it's a good idea.
