Lindelof introduced stupid contrived shit like the black goo, humanoid engineers, awful characters etc but at this point it was not yet hopeless and the franchise could be redeemed with a proper sequel that would learn from Prometheus mistakes (lack of f**king aliens most certainly wasn't one of them). Covenant writers are even worse hacks than Lindelof, our chances of getting a solid movie were close to zero after the writers were revealed. Most, if not all of the mistakes from Prometheus were amplified and new mistakes were introduced, they learned nothing! And of course Ridley shares the blame, he should have done it only if he had a strong script to work on or don't do it all. Alien Covenant should not exist, even visually it's not that interesting. It's the worst franchise legacy killer in a movie history, no prequel has done more harm. Lucas did a way better than this. .
