This show had high and low points, but all things considered, it was reasonably good.
The plots followed various parts of the comics, but they did take some liberties. I think it was for the best. Garth Ennis has some cool ideas, but his actual writing always feels like it's lacking a bit. I know it will be controversial to say this, but I really like what they did with the Tulip character. She was kind of a wet blanket of a nothing character in the comics. She's more of a firecracker in the show, but has enough vulnerabilities and character flaws that she isn't some girl-boss mary sue.

It gets slow for some episodes, but I think the show ultimately stuck the landing.
