My partner, a photographer, feels exactly the same way as you, and has been making noises about getting a bigger screen in the living room.
FWIW, I feel exactly the same way about people who can be perfectly happy listening to music on any old crappy system.
Yes it's interesting to ruminate on possible differences between movies and music in this context.
It doesn't seem to me that producers of popular music are losing sleep over the many ways people listen to music (including laptops, ear buds, etc).
Though I am aware of many film-makers who worked their butts off on multi-million dollar efforts, designed with the aim of being seen on The Big Screen, cringing at the idea of people watching them on an iphone (or ipad/laptop).
Though one can also make the argument that things are *better* now even at their worst. For much of the past, once a movie was finished it's theatrical run, it was only seen on TV - for years black and white and then even in colour, the size of the image was still small and the resolution very low. Now, though one can bemoan the size of a smartphone screen, it is still far higher image quality than old TV sets.
Over a half century old, but only just.
Ok, cool. I was simply curious if some of it was an age thing (as in you were older and set in your ways). I'm 56 myself.
I have found it very interesting to expose people to movie and music experiences they think they normally "don't care about."
I'm a bit of a fanatic about detail and presentation. My projection-based home theater has a blacked out wall around the screen, and black velvet curtains are pulled along all the walls for viewing, with the effect being, with lights out, the room truly disappears from view and it's just you and this huge, immersive image. It really does change the experience.
Plenty of people who "don't care about home theater stuff" have ended up thrilled watching movies in this set-up. They say things later like "I had to tell people about watching a movie at your place" or "Lately when I've been watching movies on TV I find myself wondering what it would be like on your big screen." They aren't necessarily motivated to change anything in their own home viewing, but they certainly "get it" when they experience it.
The same goes for two channel music demos. Numerous people have sat down to listen to my various 2 channel high end systems saying things like "this will be probably lost on me, I don't have ear for this kind of things, I just listen on my radio/phone" or whatever. But then they find themselves taken aback and utterly sucked in to the experience "never knew music could actually sound like THAT!"
I know that I'm far from alone in seeing these reactions. I bet many in this forum have had similar experiences.
