Um... What?
Neither Snyder's Director Cut of Watchmen or Dawn of Justice were released in theaters. Both of which are highly-regarded among every comic book (and every non-comic book) fan that I've ever met personally. If you don't think that better movies garner more box office revenue, then... Lol what?
Where are you getting this misinformation that Man of Steel 2 was scrapped? That's not true in the slightest. Any Worlds of DC fan can tell you that BvS was the 2nd to Superman's 3-movie arc the majority of the time... Followed by Justice League (Part 1) completing the trilogy arc of New Superman to Who Our Parents Know to be Superman. Justice League Part 2 was to be the first full-feature of the "perfect" Superman. Man of Steel 2 is still "in development" (whatever that means to WB).
I couldn't care less about RT numbers, but some people do, and the BO numbers support that audiences do in fact like Aquaman, despite it being the same exact style as Zack Snyder, except with bright colors (something that Snyder haters claimed would make critics like his movies).
Snyder's vision for Worlds of DC was great. It's blatantly obvious that he was the only one with a plan for this shared universe. Man of Steel was perfect. The BvS Director's Cut is great. Wonder Woman was very good (did you even know that he was involved?). The 1 scene he directed in SS was nice. His plans for Justice League were great (the studio cut all of the guts that made the back stories that every Marvel fanboy obsesses is necessary to a team-up film).
The fact that WB fired Snyder doesn't mean anything other than that they have literally no idea what they're doing. Their studio is a complete mess with no plans. They have no idea how to respect source material and comic book fans. As has been discussed - yes, CB movies need to appeal to general audiences - but not at the expense of the materials' true fans. Snyder is a real comic book fan who knows how to make comic book movies that can appeal to general audiences if studios don't interfere with the production processes.
All that Sucker Punch is, is evidence that he can't write stories. That's not his primary job. He has shown time and time again that he's phenomenal at directing stories, which is difficult to do successfully when know-nothing execs limit your artistic abilities.
