This image [and the others in this series] has a strong but subtle 80s feel to it. It's as if 80s sci-fi were brought into the 00s without being stripped of it's character. Obviously this is a very good thing.
No problem. Perhaps because they didn't have the special effects tech we have now there was a real drive and passion to make everything really believable, which resulted in a good style and conviction.
