This is a B movie from the 50s to be sure, but it's one of the classic B movies.
Part noir, part sci-fi there's a certain amount of camp value to this film that you just can't take seriously. Carpenters The Thing was technically a remake of this film, though more close to the novella "Who Goes There", which this film was based on.
Now considered a classic sci-fi, this movie is still a bit rough around the edges by modern standards. Taken as a movie of it's time, and foundational science fiction however, it's entirely a different thing. A good movie to watch at 12am, on a cold winters night when you're snowed in.
