Truth be told, I did go out with a couple of girls (ie not technically dated) in 2002, and dated a couple of girls in 2006 where I brought them to the cinema and again in 2012 and 2015. I haven't taken a girl out to the cinema after 2015 to my recollection. Since 2017 I got more into the modern age (ie bought a modern TV, brought a wider computer screen and a tablet). The cinema was a good excuse to interact with girls in the past (ie you could talk about movies to women or get movie suggestions from them), you could flirt with women who work in the cinema and talk about movie selections there, etc.... So I think it was more helpful rather than hurtful / neuteral in terms of encouraging interaction with the opposite sex/dating. You could also try to cold approach women in the cinema itself and ask what they just looked at, etc... or what did they think about the movie that was watched.
That being said and fast forward to today: Yeah, it's not just the TV, but you can get a movie theater experience with a VR headset where you have a gigantic virtual screen infront of you and actually trick your mind that you are in a cinema. There are also digital projectors that can project large images on a wall, and of course, TV technology.
In my experience, the TV I've had was 58 inches, but it was not large enough when watching wide-screen movies as I didn't feel the screen was large enough to begin with for a FLAT-TV, and liked movies that were either cropped for HDTV, or were filmed with a less wider aspect ratio (ie 1.85:1) which would be passable. I didn't feel satisified with the size of the TV despite I liked the image. To solve this I got a projector which put an image so large that you didn't care about black boxes on wide-screen movies as the image is very large to begin with and is at vertical image parity with the 58 inch TV. That being said, even with the projector, it really satisifed me, but it was still techncially a second place still with the movie theater. When I got a VR headset, that made an experience better than the movie theater. The VR-Headset (Meta Quest 2) was so immersive, when I reflected on the movie, I remember allot of details of the movie that was seen, not just the overall experience of the movie and felt like I was in the movie itself. Sort of like an IMAX movie.
This coupled with streaming selections have just killed interest in movie theaters with me. They are coming with more advanced VR headsets (ie Meta Quest 3) and some of the VR-apps have the capability of hosting rooms so other VR users can watch the same movie in the same theater. (ie they also have VR dating where you can meet women in VR and if you are compatible enough, meet offline and take things from there, etc....).
