Shows cancelled too soon

Any shows you believe were taken off the air before they got their due credit?

There was a show i can;t remember what it was called but it was on fox a while ago about like a bunch of demons excaped from hell , and they sent one guy to get them back and repent his sins. and he was like invincible, like he jumped of a building and broke his legs and he just poped them back. And to kill demons you had to shoot them in the eyes. and he had a tattoo for each demon. what was it called ?
