I thought I was the only one who was disappointed with Gravity Fall's finale (and the last 1/4 of GF overall tbh). Around when it aired I saw a ton of praise and love for it. Oh sure, there may have been a couple criticisms but no one seemed nearly as disappointed with it as I was. It made me sad cause I love Gravity Falls a lot, I wanted to love the finale but it just didn't cut it for me. I agree with everything in your post.
