Strategic voting sucks. Vote your favorite 25 in order.
But for 6-18 in particular, the order didn't really matter to me because they're all films I sort of care equally about. I moved them up or down the list for various reasons (what did I want to see do well but I didn't think others would place as high was one, but I also moved things based on which films had better action than others).
My #12 is also one of my favourite movies of all time, but I didn't think it deserved a spot above 6-11 because it's one of the few movies on my list people could argue shouldn't count as an action film. I wanted my list to reflect my personal taste, but I also wanted to try promote action above all else, since it is an Action Countdown after all.
