I hope the director puts the brief hesitation that Toothless has before he puts his muzzle in Hiccup's palm. The trailer doesn't have one and I think it’s a critical element to the development of their relationship.

The first few episodes were cringe-worthy efforts. As the season progressed Seth seemed to find his footing and his love for the genre. The last half of season 2 and all of season 3 were masterpieces of social and SF commentary.

I am thrilled to see if Seth and the Disney people are still discussing the possibility of a season 4.
