Lost Pilot and season finale

Unfortunately, due to human error, we didn't get to see Lost's season finale (the truth is that the VCR was set for the right time but the wrong channel). It repeated during the campout, so Megan saw it because she stayed home, but she didn't record it. But what she did see is interesting. The Pilot is on right now (as i type) and i just realized that when we hear "the Monster" for the first time... it sounds an awful lot like a machine. And when i mentioned that Megan said that made sense: the closed captioning during the finale said "gears clicking" and that there were chains involved. It just seems really weird but it kind of makes sense. The thing is, is it cloaked or what? Seems pretty strange and inexplicable. Of course, that's what Abrams has been going for...
