If you look at these reviews you will notice that everyone who gave it 1 star are people who wanted something more like the various source material or are sad that this show deviates in a lot of ways with its characters and such.
That disappointment is fair, but if you're like me and literally had no concept of most of the characters (Plenty of them go as far back as the early 60s) then the show is far from a 1-star tier show, and it's grossly unfair really that there are so many willing to dismiss the show because they don't like how it revived some long-gone and generally unknown characters to many.
