I didn't see part 1, so it took awhile to understand what and who were the characters and their roles. Personally I'm not a fan of the sci-fi genre, felt it was long movie. Glad I had my mate who saw part 1 helped fill in the gaps.
Found the story interesting, however recommend to watch part 1 beforehand. Umm the intense special effects took away the human factor for me. ⭐⭐
