What is up with birdman?

Ok so this is the film I've wanted to see most this year. The thing is it came out way back in October, and I just can't find it?! What's the reason behind this? It's driving me crazy. I've read so many reviews on it praising it, and speaking on how amazing it is, and how Michael Keaton will most likely get some Oscar buzz from it, and what not. I've seen the rotten tomatoes score, I've seen youtubers review it, but I CAN'T FIND IT! I've been to three theaters, I've searched online for it in every theater within 500 miles, I've searched online where it's playing, I even got desperate enough to try, and torrent it, but couldn't even find as much as a cam!? Why? Where did this movie go? Please help, I just want to see the stupid thing!
