Very cool list, but...
The Lost World: This is the moment, in my mind, that Spielberg stopped being a can't-miss guy. I really enjoyed both books, and was a little irritated that the filmmaker decided that he would completely chunk Crichton's story for the sequel, but I sat through most of it. The doghouse hanging from the T-Rex's teeth, though, became the first time I ever walked out of the theater mid-movie.
The Protector (one-take fight): This is much more impressive to movie nerds than other people. Sometimes appreciating why a scene is SOOOO awesome requires at least a cursory understanding of the craft of movie making, but if appreciating that a scene is awesome forces you to be aware of the film-making process, most people aren't going to get it. This scene is slow-paced and plodding, even by 70's kung fu standards. Because of the way my brain has been trained by modern cinema, rather than thinking "holy crap, they're doing all this in one take", when they didn't cut as he went up the stairs, my first thought was "What the hell is going on? I can't see anything from this angle".
2001: This scene is definitely... different. While I love this movie and I LOVE Kubrick, I've always thought that the only reason this scene exists is because he didn't really know how to make a coherent and satisfying ending to this movie. So rather than just saying, "Ta Da!" and sending the audience home, he just put a bunch of weird imagery on the screen and hoped nobody noticed he never bothered to end it.
