Why should Canada Post be a corporation at all? It is legally managed to serve all Canadians. Corporations otherwise are not legally required to serve this or that place or demographic. Yet Canada Post must deliver to as far as Grise Fiord. It cannot be profitable while legally obligated to service extremely unprofitable regions. It can either serve all Canadians as a service, or be a real corporation that can make decisions like target demographics and operations, but not both.
(To be clear, I think everyone deserves mail service, including the people of Grise Fiord, so it should be a service and not a corp.)
I watched every episode, all the seasons. It does get better over time, and the last season is the best of them (imo). I feel like they started to actually figure themselves out by the last season, but I'd still say it was okay, not "good". I think I would have liked a sixth season to see if it would have become "good".
If we think of Discovery as a drama show that's about people's relationships that happens to be set in a sci-fi universe, I guess it's an okay show. It's just not what Trek or sci-fi fans want: sci-fi. Was it a good choice to make that kind of show? Well, you know, I wouldn't necessarily say "no", but I don't think it should have been "Star Trek". You can have drama shows in space, just call it something else. Trek as a franchise has a certain level of expectation, and disappointment exists in the gap between expectation and reality.
