The first half of season 5 was completely fantastic, but I have a feeling that it will work much better being paired with it's latter half. That might sound obvious, but it really is the difference between this being Season 5.2 instead of Season 6. A lot of the first eight episodes of S5 were a slow burn; essential to the buildup of the characters and plot, but without much coming to a head (with a couple of exceptions, obviously).
All of this is to say that they have all of the pieces in place, and the necessary elements that aren't as intrinsically exciting have already been taken care of, leaving these final 8 episodes to let all hell break loose.
I haven't been this excited for the airing of a television show, like, ever. Breaking Bad is the first time I've been invested in a series as it is still airing. On the video game side of my life, the title often becomes a victim of its own hype when this happens. Here, I have no worries of that. These are masters at their craft, ready to throw down one of the crowning achievements in all of humanity's entertainment.
