Well, I don't consider myself that much of an Aliens fan, although I do have my childhood memories and traumas from watching this classic film at night. I'm not a huge fan of documentaries, but I don't completely reject them either. This one seems quite interesting, especially based on what you've shared here. It's incredible what James Cameron has achieved with this franchise during that time. The fact that they didn't use CGI caught my attention more than anything else, oh, and the fact that the Xenomorph's design was based on the art of a famous horror portrait artist and things like that. 🤔
Good recommendation.
