My vote would be for 20 movies just so I can cram as many different types of movies in there as possible. Also because I think the top of the draft is going to be pretty competitive over the popular choices but after round 10 or so we'll start to see a lot more unusual and distinctive choices which will make the lists all feel more personalized. But I'm up for whatever the group decides!
So what do the rest of you think? Either 12, 20 or don't care?
