I think I fell in great like with Birdman from the opening credits, with its lovely take on Godardian* typography. I did spend a lot of the time watching this film feeling as if it was written especially for Michael Keaton, but both the writers and Keaton deny this – after reading that article I felt a little bit down on thinking that was the case. I greatly liked the continuous takes, the clever way it was edited, the script (this article from a series on screen writing details on of the pivotal scenes and is fascinating). I loved the acting – being an actor playing an actor acting in a play must have been a tough day at the office. So yes, A-, would watch again.
* I suspect I may be re/watching some Godard films this year.
