I love that they added a narration to the Season 2 intro.
Adding a narration to the Season 2 intro, definitely made it feel like the show was coming full circle.
Especially with season 1 pretty much just being a 13 episode intro of everything. While season 2 is a whomping 52 episodes. It really felt like the writers were saying - "Ok, it's time to get serious with this thing". The lore and worldbuilding in the show still amazes me today.
