I watched a few of his videos. He likes Gotham, but he seems to hate the CW a bunch. I get it. There are certain things I don't like, there's a lot of rubbish writing, but I think Batwoman and Gotham Knights are hated too strongly. I'd argue The Flash gets much worse than either of them ever were.
Yeah, I mean, I don't like the premise of Gotham Knights, but it was clearly made by people who love Batman. The show LOOKS good, there's solid actors, great villains, decent writing, but all that gets thrown away because it's a "woke" show where Batman died.
As for Batwoman, I would have loved to see Batman in the Arrowverse proper, but it's not the CW's fault that they ended up with a bad deal. If DC were smart, they'd allow multiple versions of Batman on television to exist alongside the films. The Arrowverse was CONSTANTLY getting shafted by the DCEU. Batwoman was actually pretty decent and gave us Batman lore in a DC world that needed it. I don't think most Batwoman haters actually bothered to watch the show. It's good! Very flawed, yes, but still.
The most tragic thing about the Arrowverse is that we were so close to getting a full-on proper DC Universe after Crisis on Infinite Earths. Superman was going to be a main character in the highest budget show, Batwoman was giving us the closest thing to a Batman show they were allowed, they were implying a lot of crossover lore with Earth-Prime, we had a half-decent Justice League, and then... poof! All gone, half the shows had cliffhangers, and one was made non-canon. I know nothing is ever really gone, but I'm just disappointed that Earth-38/Prime's Superman really did end up just existing to make his cousin look better and never got his time to shine despite being the most important DC character ever.
Yep, you've said enough for me.
