The two best films I watched were The Thing and Dark City. In fact I've got a petty bias against the new Thing movie because I figure there is no way in hell it will compare John Carpenter's version (which itself was actually a remake of a REALLY bad and dated film).
Both outstanding films.
That said, I don't think it's fair to categorize
The Thing as a mere remake of
The Thing from Another World. It's really not. If anything, it's a more accurate adaptation of the novel,
Who Goes There?. Admittedly, Carptender spiced it up considerably with a ton of subtle nods to
At the Mountains of Madness. The stands on its own however, and holds up wonderfully due a superb directing, outstanding special effects, and knowing that sometimes... just sometimes... less is more.
There's really no question as to whether or not it deserves to be remade... I mean, have a "prequel" produced. No suspense? Bad CGI? No thanks. If you
really want more from The Thing, go play the video game instead. It acts as a direct sequel to the film, and does so in a satisfying enough manner.
