I'm a huge fan of this series and loved the vast majority of it (even some of the slower seasons), but it wasn't immediately clear what show you were talking about. Try adding a good title and some headings to break up the text, as it helps guide readers like me to what you're wanting to share with them.
Otherwise, great breakdown! I agree that this show might have jumped the shark with an extra season, as there was definitely a solid opportunity to tie it off. Hopefully they figure things out so that this show can have a memorable resolution rather than a miserable, quibbling death :*(
