Are these ranked in order?

No, no particular order. If I have time I'll list the rest of my faves. ;)

Yeah, I think end of November would be a sensible deadline for submissions in order to get the list posted before Xmas. I'm going to be quite busy over Xmas this year so I want to try and get everything done by mid-December.

Going to see interstellar tomorrow gonna put up my list after that incase it's good enough to make to list.
