After rewatching the series, I am not angry that it was cancelled.
The series ended on a good note. Henry and Casey were still together. Roman wrote his masterpiece. Henry decides to try and get back in the biz, etc. It was left open, but it was still a pretty neat, tidy ending for the show. For a show containing episodes that almost always end on a depressing note, the ending is actually pretty happy.
Am I the only one content with it?
Hail to the king, baby.
