Carpenter's Thing: perhaps the most terrifying movie monster ever, right up there with Cameron's Queen xenomorph..... oh my god, a nightmare made [special-effects] flesh. In fact I think the Thing was even scarier than the Queen, because it was all so.... plausible. If we ever make alien contact, that's probably what we'll get: something like that.
2011 remake has a few bad flaws.
1. We just haaaaaaaaaaaaaaaaaaaaave to have a chick in there, no plot device is too out-there to get a cute little chickie up in that research station. I am honestly amazed they didnt manage to get her into a bikini at some point. Carpenter's version was way more realistic. A bunch of guys, yep, that's what you'd see.
2. Are these scientists related in any way to those boneheads in Prometheus who go down into the Mound, look around, and say "yeah, I think its safe, let's all take off our helmets!"....? Are they blood brothers? They must be.... because drilling down into alien tissue and waving the sample around without so much as one test to make sure the tissue is actually inert [dead], as well as not carrying any potentially problematic microbes is just as bleeping stupid.
3. Ok, I could overlook all that - I have overlooked larger, stupider plot-holes if I am enjoying myself - but when they went inside the alien ship was just shark-jumping time IMO. Anyone coming out of that just does not strike me as plausible.
