The Alien vs. Predator films aren't canon as far as Scott is concerned.
no other film after "Alien" is canon either... according to Scott.
Scott honestly sounds like hes losing his bloody mind. either hes avoiding questions by rambling on about shit that has nothing to do with the question, or hes just getting old and honestly actually losing it. to me, that interview was literally drenched with "listen to my stories about my glory days, my adventures and my incoherent answers that deliberately avoid the question im being asked!"
dont get me wrong, I like Ridley Scott... hes an amazing artist and film maker, but i think hes losing it a bit in his old age and really not paying attention to ANYTHING that has been set up canon wise for the past 30 odd years either in film, comics or novels... also hes completely ignoring everything that happened in Prometheus lol
i have a feeling that the next 2 movies are going to be just as cluster f**ked and jumbled as Covenant was! at least Prometheus was exploring some very big ideas and not out right wrecking the lore and canon of the franchise (dont care what anyone says about the Engineers, they were a TOTAL mystery and I prefer Scotts idea MUCH MORE than the giant elephant trunked beings that the Dark Horse Comics lore introduced)
