I don't know what people don't like about it, but it's usually the surface narrative people complain about. Don't you recall Ridley Scott talking about "subtext". That's where the real film lies, and people don't seem to get it.
It's like if I said "The Shining is just a typical haunted house/slasher movie". There's so much going on in that film, so many layers. It gives the film a longer life as people can rediscover it. I mention The Shining because Ridley is a fan of Kubrick, even cast the bartender from The Shining in Blade Runner as Tyrell.
So all the complaints about it being too tropey, it's like that for a reason.
Oh, and Covenant doesn't need defending, if you want to waste your energy disliking a film, that's fine. There are far worse things in the world.
