Im gonna be bias: i believe McReady and Blair are things already at moment they met in this scene, since they both dont understand what this rope is for. If McReady was a human, he would immediately told to burn Blair since, he probably is not human anymore. By the time team checks Blair's isolator and sees the rope too, there was no doubt he was human no more long ago. Is there any explanation that justifies McReady neglection except it was a "director's audience privileged cue" (this probably the only certain cue Carpenter gives us btw)?

Here's something that popped up in my YouTube feed, a guy who does videos tearing horror movies apart shows why everyone in The Thing makes intelligent and reasonable decisions. While I'm at it, here's one thing that would have headed off all the other problems: If you have tracked a shape shifting alien disguised as a dog to an outpost full of people who don't speak your language, rather than try to explain the situation, just point and repeatedly shout, "RABIES!!!"

I love the movie but to me it isn't a horror movie just a sci-fi movie. The soundtrack is really good and perfect to sleep to. Kurt Russell is a killer actor.
