TV: Mad Men season 3 finale

Wow, just wow. This show constantly amazes me just by existing. When it comes to the scope of the writing, plotting, thematic depth, all done within the breakneck pace that is the TV production schedule, I can not believe it's possible to execute a show like this. This was especially true of the season 3 finale, where everything was turned around 180 degrees to set up for a completely different show for season 4.
