All you guys hating on Titanic are nuts. Titanic was an incredible movie. The story was great, and the special effects were great, and yes obviously the music was great....So that's why everyone watched it too many times....and now why everyone hates it. It won like every award it could the year it came out, and until Avatar it was the top grossing movie of all time. Your opinion is great, but the statistics just aren't on your side.
Cameron is able to write a story that makes sense.That's arguably what people hated most about Prometheus and Alien Covenant...The story.
Also I think if Cameron showed even the faintest interest in returning to the Alien Franchise they would open their piggy banks, and literally fire anyone already involved in it...including Ridley Scott.
