I ended up with 13/20. Have seen all 20, and like them all, even though I didn't quite get what others saw in Children of Men or No Country for Old Men when I saw them, but that might change on a re-watch.
If I had the chance to vote again, I probably wouldn't include Shaun of the Dead, City of God or Memento. I have seen each of them only once, and I remember putting them on my list last when I was struggling to decide what to do with those last few spaces.
Note to self: For the Top 100 this summer, be sure to put a lot more time and care into your list.
(I don't mean to say that I don't care about this project - I do, and I appreciate the effort put into it by the team!)
