And THE FLY and THE THING . . .
I disagree with both The Thing and Invasion. I thought the originals were much better.
Of course, I quite agree re The Fly, but I don't know if that can be considered a classic.

WOW! You must be the only person on the Internet who agrees with me about the remake of
"The Thing"!
That movie has a massive cult following online and I've been arguing with people about it for years. I really don't see what the big deal is. I loved the over-the-top gore (in fact, it made me laugh hard, but with affection for how crazy and imaginative it was), but I thought aside from the scenes of the creature taking all these weird forms and causing gory mayhem, it was boring. I really didn't see any interesting characters or the so-called deep messages that others perceive in the movie.
I think both the 50s and 70s versions of
"Invasion of the Body Snatchers" and the 50s and 80s versions of
"The Fly" are awesome and classic, but each in their own unique ways.
P.S. Oh, and 'A Beaker Full of Death', I'm still waiting for you to tell me where you got your amazing avatar!
