Curmudgeonism
You know, I once went to the cinema to watch a film. It was OK, it didn't change my life or anything, but it entertained me for a couple of hours, and I didn't mind paying the price of the ticket (although I can't say the same for the popcorn).
What you seem to be missing, Marvin, is that for 60p you have something that makes you smile for a bit and gives you something to show your mates down the pub, especially those with iPhones. For something to be worth a price, it doesn't have to _do_ anything apart from, perhaps, take your mind of your lot (and the feelings of inadequacy that seems to give you in particular) for a short while.
