who went in not knowing any spoilers? (SPOILERS!!)
I managed it. Beyond seeing the 'Hurt' teaser trailer and Jackman and Stewart saying this is their last movie and read that the kid was being called X23 so that must be something to do with Logan being Weapon X (also don't read comics so had no knowledge of any of those Old Man Logan, Death of Wolverine etc),
Obviously I had a feeling Xavier would die (mainly due to Stewart saying he was done and Charles being in his 90s) but thought it'd be of old age/illness or maybe Logan or the kid would have to kill him to save everyone from one of his mind seizures Jean/X3 style ..had no idea hed go out like he did.
Didn't know Logan would die..like Xavier had a feeling he would at the end (Jackman and everyone saying its his last one) but didn't know for sure.. I guess its kind of like Spock in The Wrath of Khan or Han in TFA..everyone had heard the rumours before but no one knew for sure until they saw the movie (but Logan dying wasn't as a known thing as Spock dying was back in 82)
Had absolutely NO idea there'd be a Wolverine clone (even when they were making him) so literally didn't know what the hell was going on when he killed Xavier lol (took me a few seconds to realise he was a clone and not Logan)
Didn't know Charles had killed the XMen (obviously Logan had survived it)
Didn't know the kid was Wolverines daughter (kind of)
Didn't know Richard E Grant was Strykers? son (or another Alkalie scientist?)
Didn't know when it was set (2029) or how it tied into the timeline (i.e. set after the DOFP alternate future ending)
Had no idea of the sinister plot that finally wiped out the mutants (wiping out all mutant kind has been a central theme in most of the X movies and been directly attempted in X2/3/DOFP (with DOFP they reset everything so it was good but as Terminator showed and as Beast explained in DOFP we see the dark future is inevitable) but here they finally did it with the chemicals in food stuff which was wiping out the mutant gene (in regular people so they dont have mutant kids. And with mutants making them sterile and affecting their powers - e.g Logans healing being affected so he no heal easy and is getting adamantium poisoning and left him vulnerable to his full powered clone (plus maybe his age too), and also it mustve affected Charles (in addition to his age) so he wiped out the Xmen/bunch of humans in a seizure (bar Logan who could survive it) -similar to how Stryker tried to make him do in X2. (plus maybe all the DOFP stuff that happened (the original timeline wiped, the mind meld, professors knowledge of two timelines e.g. in the deleted scene his getting confused that Logan killed Jean ) could've contributed to the Professors gradually losing his mind/suffer seizures?)
