Ranking the Episodes

So, now that we have nine episodes worth of Unnatural History, I think we have enough to start ranking the episodes. I'll put mine below, but I am really curious to see what fellow fans think. While ranking them, I realized that even the episodes I put at the bottom I still enjoyed greatly; I just enjoyed other episodes even more. Here's mine:

1.) ep7 - The Liberian Candidate
2.) ep9 - Now You See Me
3.) ep8 - Curse of the Rolling Stone
___________________________________
4.) ep5 - Fountain of Truth
5.) ep6 - Public School Enemies
6.) ep2 - The Griffin Gang
___________________________________
7.) ep1 - Pilot (The Victor Belongs to the Spoils)
8.) ep3 - Sleeper in a Box
9.) ep4 - Heart of a Warrior

For me, the lines represent in a way 'tiers'. As in the first group I enjoy noticeably more than the second group, and the second group noticeably more than the third group. Also, I enjoy each episode within each tier roughly the same. Distinctions within tiers aren't too noticeable, but I still gave them a hard ranking.

So being the stats major nerd I am, I saw some noticeable trends in my rankings. Namely, as others have mentioned, the episodes are getting better the later it gets into the season. In fact, my personal tiers were almost broken up into perfect thirds by air date, with just Heart of a Warrior and Griffin Gang switching places. This gets somewhat skewed though when you consider that Rolling stone was supposed to go second... all said and done though the general trend of episodes getting better makes sense as the cast and directors get more comfortable and acquainted with the show.

So what are other people's lists? Any comments, questions or criticisms of my list?
