Loved the first 3 seasons…

And I just started the 4th season, and after the 1st few episodes of the 4th season…what the hell are they doing??? This is awful! 30 years into the future? A random surprise daughter? Characters from the rest of the seasons just disappear. LOADED with preachy political bullshit. How many times can they mention climate change in one season? Don’t know how long I’m going to last with this season. What a bummer. Swing and a miss!
