Yes I do! My mom and dad have always loved watching many old movies, so that's how I was introduced to them. It was one of the ways for us to spend time together, but I came to like those movies for their own sake too. :)
But it depends on the individual movie, of course. Just like some of today's color movies are amazing while others are really crappy, the same goes for old black-and-white movies. It all depends on the script and story, acting, execution, etc.
The famous classics like "CASABLANCA" and "GASLIGHT" are well-known of course, but there are also some great (in my opinion) black-and-white movies that are not so well-known; it's worth exploring the filmographies of some actors/actresses that you like from the era, and trying out a few of the more obscure ones. That's how I found some great gems along the way that are not so famous. :)
I love black and white movies especially silent films. I binge watched silent films once when they were on TV before binge watching was a thing and before social media was a thing or at least in its infancy.
