I'm crazy about Creature From The Haunted Sea, and that fact that a lot of MONSTER COMEDY fans (the target audience, in other words) don't like it, makes me like it that much more. Like being in some small fraternity or something.
One that I could name is End of the World with Christopher Lee. It's full of real disaster footage, but then it ends with a really fake-looking volcanic eruption. The problem with picking on that is, I HATE seeing real disaster footage, so I prefer that fake (and fake-LOOKING) eruption, and wish the whole movie had gone that route!
