For me personally, I grew up with Marvel AND DC, and like both properties equally. My older brother was an avid comic collector and so I read lots of his DC and Marvel books before going on to collect a bit myself. Loved Batman, TAS, Batman Beyond on to Justice League, Young Justice, the animated movies (which I still watch), etc. Watched the first few seasons of The Flash, before it lost my interest, few seasons of Supergirl, the Nolan Dark Knight Trilogy, and on and on. I WANTED (and still want) DC to produce a cinematic universe on par with what Marvel has done.
Obviously, this is all subjective and people are free to enjoy what they like. If they liked the Snyderverse, then that's their prerogative as much as it is for people who didn't enjoy it. Personally, I felt that Snyer was all wrong from the start and I had bad feeling that his "vision" would end up being a disaster. I was sadly correct. Snyder has a misunderstanding/outright disdain for a lot of what makes DC special, and his commentary and decisions on various matters concerning it illustrated this (Batman would be raped in jail in my movie, killing off dikk Grayson before he even became Robin to start that universe, killing Jimmy Olsen as an afterthought, etc.). A lot of his casting choices were baffling - Ezra Miller, Eisenberg at the top. Momoa gets by on charisma, but is a far cry from the source material, Gadot can't act and even if some people enjoy her in the role (I never did), there were other much more charismatic actors that would have done far better. I did enjoy Cavill, but he was saddled with a mopey, depressed Superman for most of his tenure. Affleck was serviceable, but don't get having a Batman that age to START your cinematic universe.
At the end of the day, regardless of one's personal feelings for the Snyderverse, the GA checked out. Wonder Woman and Aquaman were anomalies, but there never was a sense of a brand loyalty, rather people decided those movies were good but it didn't translate to wanting to support other movies in that universe. It's had like 6 flops in a row now.
It should have been clear a long time ago, but most certainly now that this universe is dead. There is a big difference between those that enjoy the Snyderverse and DC fans in general. I'm no less a fan of DC because I feel the same way most have - it didn't work and hope that Gunn, against a rather large tide, is able to right the ship and put together movies that are not only good, but have wide appeal. DC's characters deserve that.
