You've gotta see this. Amazing on every viewing.

I don't think there's much to say about this movie that hasn't already been said.
This phenomenon of a picture has two main selling points:
The magnificent practical affects that make a lot of recent stuff feel old fashioned. I feel like I could reach out and touch the things being show (and I could have if I was there). The technical proficiency and the grotesque imagination is perfect for anyone who obsesses over strange organisms. It's striking no matter how many times I rewatch it.
The other selling point is that we have a solid piece of horror story telling here. In the isolated wilderness, the routine lives of some scientists finds something that they could never have anticipated. From the very earliest scenes with a helicopter shooting at a dog there is a feeling of unease and mystery that quietly festers among an oblivious crew (but who could have seen it coming)?
It loses none of its power as it transitions from chiller, to science fiction masturbilia to taut thriller where you don't know who to trust.
If you haven't seen it just see it. This will still be fresh 50 years from now because of its intelligent, folkloric writing and expertise.
