Critically panned when it came out, and my favorite horror movie of all time. Of course critics feel differently now, but far after its following grew.
It is made by the practical special effects company originally hired for the 2011 prequel, who were then fired and replaced with a CGI company. They were so disgruntled they made their own off-brand The Thing movie to show off what they got. The plot is kind of meh, but the effects are amazing for fans of The Thing.
