There are a few theater operators that have figured out that just showing the movie and selling expensive popcorn isn't good enough. They have to have comfortable seats, decent food, great drinks, rules against talking and using phones, and reserved seating. When the experience is good, I'll pay to see movies I already know well. For example, I just went to see the original Blade Runner two weekends ago.
It's a little like how I can watch baseball on TV, but every year I still love to go to the ballpark to watch live. There's more to it than just the thing you are ostensibly there to see.
So I agree with you. They should have same day streaming. For people that like going to the cinema, they will still go.
I also think that on your way out the theater, they should have DVDs and BluRays of the movie you just saw for sale.
You're right that they should make it easier to consume their content but they should also try making something watchable first.
Having Netflix and Amazon but movies to distribute directly day one may help. They’re offering things to theaters but theaters want to hold the line.
