Very true. Popular perception certainly means something... this, at times, can be at odds with the director/artist's intent. Occasionally the popular mindset eclipse's the original intent as well. Interesting to think about. I always considered The Thing a remake until I read that it was an adaptation, but I am not sure if those were Carpenter's words or not. Maybe it's both and I'm overthinking this.
As I recall, the 1980s THE THING visually homages a scene from the 1950s version at least once: when the men fan out around the buried spaceship only to discover that, holy cow, it's a flying saucer!
There's also an odd double standard when it comes to classical versus genre fiction. A new version of a literary classic such as PRIDE AND PREJUDICE or LITTLE WOMEN is not really seen as remake, but a new version of PLANET OF THE APES or LOGAN'S RUN will invariably be perceived as remakes of the original movies, even though those films were also based on novels, just like LITTLE WOMEN or THE THREE MUSKETEERS or whatever.
