Is that based on the novel I, Claudius? I was forced to read that in high school, it'd be interesting to see a TV series.
The Office (US) is another show that could have benefitted from an earlier cancellation. Not that the later seasons didn't have good episodes and a lot of good new characters, they just kept stretching to figure out where the hell to go with their character arcs. Get Jim and Pam together, good, done. No need to make up a new good guy/bad guy love triangle every season and come up with more new ways to have Michael act needy.
Also, if Community were cancelled after two seasons we'd have more to complain about, like with Firefly. Complaining about Community's cancellation would have been fun, now we have nothing to complain about.
