I didn't see a thread for this so I figured I'd start one. I only started getting into it religiously last year. Before that I had seen a few episodes here and there and thought the writing was brilliant. My wife was away one weekend last summer and I decided to start watching it from season 1. That weekend I finished the entire first season. It left me wanting more. Instead of going into the second season I watched some parts of the first season over, picking up on little things I missed the first time around. After the second time around, I realized I was Hank - well 90% of him. The women don't come as easily anymore (being married and all) and his writing is somewhat better than my own. Anyway..
Some great cameos throughout the series include Rick Springfield, Marilyn Manson, Tim Minchin, Kathleen Turner, and Rob Lowe - just to name a few. The upcoming final season is going to have cameos from Heather Graham and Michael Imperioli. It sucks that after going full ahead into this show that the ending is already upon me. I'm curious as to how they will end the show. I suppose there are a couple of obvious conclusions but we shall see.
