Even including both candy bar purchases AND a somewhat-nice meal while I am out, the amount I have spent on going to the movies in the last few years or so is nowhere near the cost of a TV and surround sound system good enough for me to not want to go to the movies anymore.
To be fair though, the cinema I go to doesn't have the problems oft-cited here on Slashdot. The ticket prices and candy bar costs aren't obscene, the seats are comfortable and I have never once been in a session where other patrons have ruined my experience.
