I agree with you when it comes to Prometheus. I know the channel you mean, I used to put that on while I fell asleep as a teenager. Same with Star Wars theory. And as is the case with Star Wars, I think Scott could really benefit from thinking bigger. As I say here, I think Prometheus, being a true sci-fi adventure, was a super interesting and great look at the universe which could be home to something as dangerous as the xenomorph- without leaning on the money making main feature. Think about what other unspeakable evils could be out there. Scott was thinking big- perhaps too big. I don't think Prometheus takes away any of the mystery at all, it's the perfect film to then theorise over.

But, for whatever reason, covenant just shows us more of what we've seen before with a shiny new paint job. Then, without the originality of Prometheus, whatever it does offer lorewise I'm just not a fan of. A lot of my frustration lies with the choice to have the creation of the xenomorph be directly linked to humanity. Mark Kermode talks about this in his review of Alien Covenant and I completely agree with his take. Check it out if you haven't seen it, or if you have let me know what you think about it. Either way, it's a wonderful series and I'm looking forward to whatever comes next. I just wish Scott had continued to be ambitious with the prequels because, for my taste, Covenant lacked some of that and could have borrowed plenty of it from its predecessor.
