Back in the days, AMC was one of the true gems. Clean prints, uncut, no commercials, and a host who introduced each feature. If I remember correctly they claimed to "respect the movies". I remember Saturday mornings with my kids watching Betty Boop cartoons and Popular Science shorts. The closest thing now is TCM.
Once the commercials and hacked up prints came, they were dropped from my favorites list.
I was thinking the same thing... I still have some movies from AMC recorded on VHS where the movie is introduced by a guy in a reading room/library where he talks about the movie, actors, and some history about the film. I loved that, but when they started adding commercials and dropped the intro I lost interest. AMC was definitely a gem in its prime, but as most channels it's become over commercialized.
