Wow, who do you think you are - JC himself?!? Oh, wait, right...
Sorry, this is like the bottled water man sayin' the that tap water sucks - the only way to experience real water is from their tap, poured into a plastic bottle, and then cured with the chemicals leaching from the plastic into the water during all the time it sits on a shelf.
JC profits from ticket sales and, as has been mentioned, the now far too common practice of movie release, movie release with a toy surprise in the box (just like kids cereal - it still works!), extended movie release, special features movie release, director's cut movie release, director's cut movie release with toy, boxed extended director's cut with never before seen footage, the raw footage release, and then... its time for the 10th anniversary versions of the previous cycle (and 15th, and 25th, and so on).
Of COURSE he wants us only to see it in the theater, rather than get it on Netflix where I can stream it on my laptop connected to a projector rented for free from my school to a sheet hanging from my ceiling to make a 100" screen. Sure, not the best, but it gives me that old-school drive-in feel.
Now, for you videophiles, go ahead and pay $10-$15 per viewing in a theater with all those other annoying people and give him a fat check. Also, if you can afford a 80"+ HDTV in your own personal home theater, enjoy all that quality. For me, I don't care if I can see the sweat pool in Jack's pores before it drips down, I just want to see how the authors are going to tie in all the elements they created while showing LOST. (Something I only just started watching last summer when I was able to stream all the episodes online in all their poor standard-def quality...) I actually would rather watch something that had good dialog, good plot, and good acting than watch someone else's video game playing session or a non-stop music video (yes, I am pointing my finger at you Underworld). Visual eye candy is good and all, but give me a good documentary any day instead. Heck, better yet, give me both - I'll watch 'em and be entertained by them both.
