I've watched the first couple of episodes. As AH goes, this is very much at the comedic end of the spectrum, mostly because the president of the Republic of Quebec and his underlings come across as utterly incompetent--but then you remember the sort of people who actually are in charge OTL and suddenly it's not so implausible anymore.
One example: the plot involves trading a slice of Quebec territory north of the 56th parallel to the US in exchange for some Florida coastline, and before it's even seriously been looked into, the president's wife has already bought herself a Florida condo on the government's tab. Haha, surely that would never happen in real life.
Also I wonder if the population of Quebec being shown to have buyer's remorse over choosing to leave Canada without thinking it through might be a dig at a certain other referendum in recent memory.
