For the most part I agree, though being less dark than Acting Lessons is a very low bar to clear.
That said, I do worry we are letting where we WANT the story to go cloud our judgement over where it will go. The narrative digressions about Bella and doors in Episode 3 are certainly ominous, and there's no shortage of other topics that could take a grim turn if DPC wanted them to.
I don't expect anything as crazy as, say, Maya to accidentally gun down Jill when Quinn finally drives her over the edge. But I could definitely see things like Maya being forced to withdraw from college and stuck under her father's thumb, or Sage taking the fall to protect the HOTs. Things that, even if we could avoid some of them, would still leave a very bittersweet taste when all is said and done.
Really, it comes down to whether this is a genuine lighthearted farce, or if it's only pretending to be one to amplify the shock when the real world intrudes on our fun. I'm certainly hoping for the former, but I can't rule out the latter until we get much closer to the ending.
