30 is a bit steep considering I have to supply my own screen, sound system, AC, and seating. Not to mention clean up after myself. Home theatre's have come a long way but some movies deserve "the big screen".
Disney is cutting out the exhibitor, and taking some of the cut for itself, not passing all of those savings on. It is passing on some, especially if you have a family of 4 or 5 that will watch.
That said, there are bonuses to this. No chatty Cathy's, or phone users to interrupt you (other than your own family). Cheap popcorn and drinks. Can pause when you want, need too (kids acting up, little Jimmy needs to use the bathroom).
iTunes used to do early rentals for some in-theatre movies (more for indie type movies) but it was a more reasonable 20... It was only a rental. This you "own" but also need a Disney+ sub to access it... probably the biggest turn off.
If it was $30 to rent from itunes, no sub require, maybe.
Does anyone know if it will be 4K/DV/HDR and ATMOS enabled? You are paying for a summer blockbuster, hopefully you get blockbuster technical quality.
Disney+ streams are quite good, but its still not as good as a disc copy or the theatre...
