Re: why is s6 > s7 ?
Is any of this really relevant, however? Let's return to some substantive discussion, please...
I'd rather watch seasons one and two vs. seasons six and seven everyday of the week and twice on Sunday.
Seasons one and two had a fresher universe with more interesting characters, better direction, music and lighting.
