I've tried to learn to never to trust trailers, but this film looks extremely formulaic and schmaltzy and kitschy. There's no indication that they tried anything interesting in terms of story. But I could be wrong, because trailers seem to be designed to turn me off these days.
I will always give Linklater the benefit of the doubt for his films. I don't always love all of them, but he's always exploring and after Dazed and Confused, he gets a free pass from me for the rest of his life.
