Ticket prices were rising long before downloading became a practice because home viewing with vhs and dvd rentals were cutting into movie attendance. This is no different than what has happened with music sales--technology has changed the nature of the market and both the music and film industries will have to adapt. And it's already beginning to happen--just as music can now be downloaded for a small fee from sites like the iTunes store and others the same will likely begin to happen with films. You can already do it with TV shows.
I will say this that if I really like a film and want it as part of my video collection then I will pay because I want the best quality transfer as well as sometimes the extras that come with the dvd.
Ahh Rationalization..the way all criminals justify illegal actions..
No different than "every body's doing it" or "If I don't someone else will"
I hope you don't ever find my wallet with credit cards in it..you stand a good probability of rationalizing the use of my cards and ID...
