THE ORIGINAL IS NOT THE JOHN CARPENTER VERSION IT WAS ONE MADE IN 1888 WITH AN ENTIRELY DIFFERENT NAME!!!!!!!!
Sorry, it just seems like whenever someone mentions the Carpenter version as being the "original" when compared to this movie people have to make that statement.
I don't think we're clearly told what happened to The Thing in the crash of the helicopter, or even how the survivors got back from the supposedly inaccessible crash site. It's probably a genuine plot hole in the movie.
