I rarely notice that stuff until a 2nd or 3rd time watching a movie. If I really love a movie, I'll watch it every time it comes on. Some movies I've seen hundreds of times. Some movies are so well done, I still notice new things in the background that I hadn't before, watching for the 89th or 103rd time.
I love old movies and am getting to the point where it's hard to find one I haven't already seen. I'll take that stuff over a bunch of special effects or so much editing that I don't even know what's going on, who's fighting who, who's winning the car chase.
