Had an evening at the charming AFI theater and I recommend both movies:
Birdman - Michael Keating looks like he's having fun. Not a very grounded movie which makes it feel light for a movie that seems like it is trying to be deep. I like that. I'm not wild about the ending, which isn't bad but didn't really do anything.
The Imitation Game - Engaging as DominicCobb says. Keira Knightley doesn't serve much of a purpose which is only aggravated by how absent she is from the movie. I'd rather watch Cumberbatch anyway... [awkward segue]... The spotlight is swiveled to political messaging a bit heavy-handedly in a way that detracts from the focus of the movie, particularly at the end in a postscript, but I don't think many viewers will notice or care. Some creative liberties are easily forgiven, like the name of his machine which serves to highlight his personal struggle.
