The clothes and the likes are really the only thing that date this film. 35 years old, and it still holds up well. No CGI featured, and none required. I have not read the book of this film, so I cannot say if it is an accurate adaptation, in the spirit of the original. I will say that it is a well-produced piece of fiction. The plot is quite good. The writing is good, and has very realistic, great moments. Dialog is well-done, and delivered equally well. The characters are credible and well-written. There is a reasonable amount of development and background for them. The special effects are undeniably excellently done. They are convincing throughout. Nature itself becomes the threat, with realistic physics. The camera-work and editing are nicely done, save for an awkward cut or two. Cinematography is effective. The pacing is solid for the whole film. As far as the technical aspect goes, the film is great. The acting is of high quality.
