I liked Season 3 more upon the second viewing.
I think the Dr Ford score from S1 might be my favorite piece of movie/film score ever. Yes, that's saying a lot.
This comment on YouTube about it makes it even better.
"I like to think of this piece as telling the story of Arnold and Robert. From 0:00 to 2:20 is when the park was created. Arnold is the violin - lyrical, emotional, and sad; Robert is the piano - clear, precise, and confident. Together the create a beautiful duet, until Arnold dies at 2:20. Then, the artificial notes come in as Robert creates the replacement. And from that moment, little dissonances and minor keys enter the melody: no matter how large or grand it grows, there's inevitably something off, something wrong that can't be fixed. It's never quite as pure or as beautiful as it was at the start - just like the park itself."
