I'm the opposite. I mostly choose to see big budget films released in IMAX which isn't very many. All of the rest I think that I agree- the home experience is satisfying for the vast majority of other films.
I don't think the home experience is already fully competitive without spending a lot. Just that the theater experience has enough inconveniences that it's getting close. For things like very wide/large formats and immersion maybe when VR gets really good resolution it will be competitive but I agree a theater still has the edge.
