I checked it out. The back-to-back first two episodes are good. I like how Phil completely gave up on life, but that it was a very slow burn. And then Carol shows up with her obsession with rules (which probably kept her going). But then she starts giving up after seeing no hope for Phil... and seeing her start to give up provides Phil with the motivation to seek betterment.
Granted, I'm not referring to "betterment" of buying into Carol's notion that all societal rules must be followed. She obviously takes shit to extreme after being alone for so long. But she at least reminds Phil that there should be SOME rules (ie: He might shoot windows for shits and giggles, but he wouldn't burn down a church). And having SOME rules... and a person to spend time with... can lead him up and out of the emotional dumps. Also, their bickering is generally funny. After following their own solo codes of life for two years, the petty ideological differences lead to some thoughtful conversations... all done with the right amount of eye rolling and comedic hatred for each other.
That all said? It almost feels like we are two episodes away from finishing this thing. I do not see where the story can progress for a whole season.
