The characterizations seem okay and I like the style (which makes it FS), but the show is uncomfortably close to home on a few things to the point of cringeworthiness (which makes it HS)
Ergo, I vote Opt. 3 as a compromise.
I don't know how it can possibly make one feel 'cringe' since its meant to be amusing and sentimental but I obviously don't know your experiences. Maybe cringe isn't the perfect descriptor either if any word does exist for your negative feeling.
Take for example, the artistic beauty of the Society of the Blind Eye episode - Fiddleford's unfortunate loss being such a teaching point for Mabel and really all of us about how important the wholeness of our life's experience is including the highs and lows. You don't get those really important messages hammered home so effectively in children's television very often.
And then the simple innocence of an uncountable number of episodes plus the adorable side characters with the absolute quirkiest puns. To think that I might have missed all of this if I didn't immediately hear Kristen Schaal's voice the very first time this ad ran through my television. So thankful.
