What movie did YOU just FINISH watching?

I had heard of it when it came out, but never watched it before. I didn't really know anything about it, so the three-part story structure of it came as a bit of a surprise to me. I mean, obviously movies generally have three-part structures (beginning, middle, end), but the fact that this was told from three different perspectives - a different one for each part - intrigued me. I'm not sure which part is regarded as the 'best' by most people, but I think I was most interested during the middle part with Bradley Cooper's character. 

Thanks for the Scarlett Johansson movie recommendation. If it's ever on TV here, I'll try to remember to check it out.
