I know everyone has their movie.. The one that you have to leave on, no matter how many times you have seen it, what you are doing, the last time you saw it... anything.
For me, I would have to say that my movie weakness is the Shawshank Redemption (or as we just call it "the shank").
Its great, because its on TBS or TNT practically every other day.
What movies do you guys have that just suck you in every time?
