The ending was pretty bad, and the way they handled Dr Manhattan was all over the place.
The ending was fairly meh, if a multi season show built up to that end I wouldn’t like it but a single season like Watchmen was and it’s ok. I do think that ties into the other issue though, with Dr Manhattan it’s almost impossible to have any kind of stakes because he’s just so powerful.
You kinda need to have him not really be part of the story but then it’s Watchmen, you can’t just not have Dr. Manhattan.
That may very well be, but the fact is that most of the 0.5/5 reviews are just annoyed by how "woke" it was.
I specifically remember let’s call them, a section of the internet, being very annoyed that the Cavalry were wearing Rorschach masks despite in the graphic novel Rorschach being a racist, misogynistic, overly aggressive well, tosser and the archetype of the alt right.
It’s particularly funny in the case of Watchmen because literally all of them are deeply flawed and should really not be rooted for, and that’s the entire point.
