Any idea why they are some of your top favorites?
A few that come to mind, right off the bat, for me, as all-time favorites, and in no particular order, are:
Alien (the original, the first one: a favorite because I could never have dreamed anything about that one up; it seemed totally new, esp. the first view of that ship (soooooooooo cool - was it animal, vegetable, mineral, mechanical, or a combination? Eh? Huh? Wha'? I said to myself.) It's a favorite of my wife's, too (!) Just about every scene was jaw-dropping, literally, for me.
No Country for Old Men. the acting; the characters; the story-line; remarks like, "You can't make this stuff up; I dare you to even try."
Now, Voyager. (No idea why.)
Passion of The Christ I felt it.
King Kong (the original) Kong himself; the dinosaurs; the relationship between Kong and the Fay Rey character.
The Thing (circa 1951) (based on the novel: Who Goes There? Saw it when I was seven; it blew my little mind.
Frankenstein (the original) Total ATMOSPHERE. I swear, as a kid seeing it for the first time, with my friends, I could smell the mouldering corpse of the Monster.
There are more.
