There's more to 'Canon', surely, than just "the same guy directed it", "the same monster turns up" or, "It's got the same title fer chrissakes!". There has to be CONSISTENCY!! And yes, I mean that in the simple, old-fashioned sense of Logical Consistency. Alien was brilliant, Aliens was also excellent, and while we were definitely on ground that was sloping very sharply downwards with the awful Alien 3 and the execrable Resurrection, there was a line that could be traced through those films that made a kind of sense. This courtesy could even be extended to Alien V Predator, though, admittedly, that is somewhat more problematic. AvP is, however, a better movie than either A3 or Resurrection. Prometheus was a mess, plain and simple. Raddledly Scott thinks he signed up for a series of Blade Runner movies. He remembers directing Blade Runner. He remembers it had a very glamorous woman with a man's name in it. That made him laugh. Raddledly loves to laugh. Sometimes, over his cocoa at the old folk's home, he pretends to be a big-shot director. Then he comes out of the home and it's our turn to laugh. Sadly. Covenant is not canon, not because it's utter shite - which it is - but because it doesn't make any sense, it's sloppy, stupid, and it's the wrong film!! You can't make Deckard - sorry, David - making the Aliens MAKE SENSE. You can't squeeze, twist, warp, or constrict the timeline in any way that make any of this garbage come out right vis-a-vis Alien. Some theories have emerged that there will emerge ANOTHER species - and it will be THIS, NEW species that made the Engineers, humans AND the Aliens. Somehow, maybe, this could be made to work. But this is really reaching. Let's grimly accept the horror that is Prometheus, and like any healthy body would, simply reject the ridiculous and laughable farrago that was Covenant. And will somebody please get Mr. Scott his favourite plaid blanket and see him back to the Home? He's just getting over-tired now, and you know how cranky he can be when he hasn't had his cocoa.
Here at Scified,it's always heavily debated what's Canon and what's not.While there is an official Canon,most of us boil it down to personal preferences.Me I widely accept almost everything with the exception of the AVP movies.That includes all Four main Alien movies,Prometheus,the Fire and Stone series,and Alien Isolation.There are other things i accept such as The Out of The Shadows trilogy,that i haven't read yet and of course the upcoming Alien Covenant.How about you guys?
