The big difference maker imo in movie theater experience is size and sound. You still need to drop about the same few thousand dollars you had to drop in 2002 to buy a proper projector and sound system today. 85 inch low pixel density screen and a sound bar ain't it, but if it is it for you, you are probably no discerning audiophile who would have probably have been fine with whatever was sold in a comparable market segment in 2002 (refrigerator width crt displays were in fact all the rage and very desirable at one point).
