I tend to get invested in the movies/games/tv shows i watch. Which is mostly why i can find enjoyment and be forgiving of less than stellar forms of visual entertainment. Just give a reason, thats all i ask, even if its utter tosh. its when they don't explain thing, either directly or through implications, that i get annoyed. I'll swallow it, just try to sell it to me. It those ones that try to be all metaphorical, deliberatly leaving out details to make their work seem all artsy-fartsy, and more significant than it really is. (yeah, i'm looking at you kubrick)
