For me and the girlfriend its 15 bucks just for admission, that doesnt include the 30 minute drive there from her house, or the 20 minute drive from my house to her house.
Renting is better IMO, Id rather stretch out on the couch and get cozy with the little lady than sit upright with an armest with a giant cupholder in between.
Although the bigscreen and surround sound are nice. But you can versions of those for your house, and it wouldnt take long for a decent surround sound system to pay for itself if you factored the cost of renting a movie vs going to the theater.
