Best scene in the movie...and one of my favorite special effects scenes ever, was when Clark's alien replication was getting roasted by the flamethrower, and the neck stretches over the edge of the table, separates and drops Clark's head on the florr, where it immediately sprouts 6 legs, two eye-stalks and skitters out the door, prompting the great quote from Childs as he turned to watch the human head-spider go out the door: "You've gotta be fukkin' kidding me!"
Yeah, that was a great line.
Both Ms. Dave and I agreed that the cool scenes were especially cool. I was wavering between 3 and 4 stars. My favorite part was when MacReady was testing the blood samples.
Don't get me wrong -- a good movie, but I'm always thinking how I would've done it differently.
Also, regarding the Scooby-Doo comment, I'm okay with MacReady figuring those things out, but I always thought that the pacing in those scenes was a little weird. ...some exposition would've work, as he kind of talked it out to another one of the guys.
