I'm glad it happened to La La Land maybe they know how I felt after the ending for that film. If there was ever a case of an ending ruining a perfectly good film it would be that. I went to see it because I thought I'd enjoy a light hearted musical sadly it wasn't that despite being sold that way.
The oscars wind me up as well and gave up on them years ago a few times genuinely good films get by but some are completely overlooked for either not being mainstream enough or too mainstream.
I do however want to watch Moonlight mainly because I find Mahershala Ali very watchable.
