2007 is my favorite, I was a big fan of this show from the first time I saw it.
2008 is a close second, another great show.
2009 I've only seen this show on the fan network, but I really like what I see and hear this year.
2006 took a little time to grow on me, but in the end I really liked it.
2005, same as 2006.
I haven't seen any shows before 2005 enough to rank them...I should go check some of those out.
