The dreamlife of me

I've never been able to remember endings -- books, movies, you name it. Ask me who did it, and I won't be able to tell you. I'll be able to describe the story in pretty good detail, but my memory will taper off just before it becomes obvious what the actual ending is. It comes in handy for not spoiling things for people. However, today I couldn't remember the plot of The Dreamlife of Angels. I was pretty certain I'd seen it (and, after reading the reviews, I definitely have), but I couldn't remember anything about it. I remember it was sad in the end. That's all. This memory failure is either because the movie is French or because I'm getting old. Next movie I forget we'll know for sure what the causality is.
