It's not the slowness that bothers me. The first season was "slow" too but almost every character in season 1 was immediately entertaining. Most of the characters in season 2 are... it's hard to explain, like everybody in the show is so concerned about something.
Alright, season 2 was actually incredible too. I thought the final few episodes were STRONG, particularly the finale. I also really like the way it expands on the mythology of the show. On a whole, tho, I still think I enjoyed season 1 more. I'm kind of at a loss just thinking about what they're going to do to top this ridiculousness in season 3.
