I have never seen Independence Day. (Probably the only person on the planet who can say that!) My favorite sci-fi are the real old black and white movies. Them! is one of the best of that genre. I also like the hokey ones where you can see the zipper on the creature's costume. :o) They're the best!
I love 50's SF, including the bad ones, but I love the good ones, too. One in particular re-uses the War of the Worlds ships, called Robinson Crusoe on Mars. Terrific movie. Also a huge fan of Journey to the Center of the Earth, Time Machine... I love the sense of wonder.
Ack, we could go on about this all night. I have a Heinlein book on the to-read shelf--am getting back into old SF novels, the new ones stink.
