Speaking of movies/shows that cannot be found, I have memories of something I watched probably no earlier than 1992 and perhaps later than that. Several scenes stuck with me because they were so strange.
One scene involved what looked like a boy-scout troop leader sinking in quicksand while his troop reached out in an attempt to rescue him. Another scene involved a group of pirate-ish people using hooks to climb a massive rope at the center of an old stone tower. As one of them leaps onto the rope, it pulls a bell and alerts a king or sultan at the top of the tower, who is immersed in a noisy party.
It's a strange memory, and it's annoying that I cannot find this show/movie. It seemed to have pretty good effects as well, and felt kind of like an 80's movie.
Anyway, the last movie I watched was Guardians of the Galaxy. Everyone talks about how fun it is, which is true, but the first scene can be pretty tough emotionally, especially as many people have personally been affected by cancer. That whole first scene, while necessary, is very jarring.
