I'm watching the Cowboy Bebop movie, since it has Halloween themes in it. It's been a while since I saw it, so I thought now's a good time!
I was thinking of also re-watching The Thing if I have more time before I get too sleepy. Though, I think it might be more sensible to watch something lighter, since I'm trying to knit while I watch and intense movies make me completely forget my knitting and just stare at the screen.
//Edit! Forgot to say, I don't normally save anything special for Halloween but sort of just pick up whatever hits the mood. Though, I do prefer old favourites to new ones.
