I'll answer your question. It's the epitome of style over substance. It's complete stupidity for the sake of being cool. Why are there three evil alfreds? Because there's a billion evil batmen all from different universes, all from different backstories, some of them got to keep their alfred.I can't even comprehend why anyone likes this shit. It feels like a giant mockery of decades of memorable comics. Like Scott Snyder is playing a demented game of Madlibs and seeing if DC will publish it.
Three Evil Alfreds? What hell is this?
Just like how Owlman had The Outsider I believe.
Now if shit like Death Metal was trying to be serious, then yeah, it'd be legitimately bad and awful.
But it has a Batman that transferred his consciousness into a robot T-Rex. A batman that was from a planet of robots and was its own sentient form of the Batmobile. A batman that is C'thulu. It's not trying to be serious, I mean the main fucking villain is called THE DARKEST KNIGHT. It's just throwing as much cool/visually appealing shit at the pages as it can and not trying to be smart or deep or meaningful. Which in my opinion, as long as it's aware of that fact, which it certainly is, is fine.
If that's not your kind of thing, which it may very well not be. That's fine too.
