I'm on the fence. I personally make an experience out of the movies I watch whether I stream it on my laptop, watch it on my tv, or go to the theater. I can't often watch a movie (or pass fair judgement) until I've *seen* it, literally, beginning to end. I've never watched a Tarantino or Kubrick movie on a theater screen, and I cannot say the works suffered for it. However, by the time I saw Isle of Dogs on a massive IMAX screen, I suffered some serious uncanny valley weirdness. That's not supposed to happen to me because I AM a stop motion animator lol.
I saw Mandy at my local arthouse theater- the place was PACKED. Sure, the speakers were... not AMC quality, there was a run on the projector screen, but the film was all the more powerful because of it. At one of the high points of the film, the audience went nuts *cheering* as Nick Cage fought his way to the end.
Movies are an experience for me. The screen size won't take that away.
I do tend to think that movies made for streaming platforms are typically of a lesser stature... but then in all seriousness... Hollywood disappoints me too.
It's a toss up. I think Spielberg is damagingly out of touch and has been since the early 90's.
The theater experience is important, but it's not the end-all be-all.
