The recasting is a good idea that would probably have gone a long way. Some of the worst acting seemed to be from the actors being "aged" the most - Ed, Margo, special nod to Danny for youth award in this category. The writing issues I had weren't with the handling of modern issues but the just horribly unbelievable stuff. I'm all for suspension of disbelief, like I had no problem with Korean guy. But everyone on Mars knows Danny is a junkie yet Ed continues to assign him mission critical stuff? And then mechanical dog guy leaves him to monitor the thing that could kill everyone? So that what? He can cross the room to work on a laptop that could have been moved to the mission critical desk? I understand when writers want to move a story along. But c'mon!! Anyway, yes, it has been picked up for a 4th season. Inexplicably season 3 got the best ratings of any season for the show. Whadyagonedo?Ok, I hear you and agree. I think the writers faced 2 problems. #1 they really shouldn’t have kept the same cast for 3 seasons. What made this show great was it was a look into an era and how a group of astronauts (& staff/families) dealt with losing the space race, continuing it in a different direction. Once it got too far into the future, you need to re-cast. There’s needs to be a new generation of people dealing with the aftermath of the choices of the first generation. A couple of players in management positions and a some cameos would have been better than finding absurd reasons to drag the whole cast through history Forrest Gump style. #2 as they’ve now created their own branch of history, they are closing in on modern politics. Such as gay rights in the 90s and their own take on the Oklahoma bombing. That get’s a bit sketchy because it’s still relevant compared to the Cold War & Space Race, even Vietnam where there’s a consensus among 90% of the population about how to perceive those events. Season 4 will have to deal with terrorism and the war on terrorism at this rate. A transgender astronaut. It’s not sustainable. Honestly, I’m glad they got as far into history as they did, but they should have either wrapped it up in season 2 or totally re-cast (with 1-2 actors remaining) for season 3. IDK if it even go picked up for season 4, but you and your wife (& I) will all be enjoying the cringe some more if it does.
