So I basically set my enjoyment of TP season 3 on not really giving a crap about figuring out the rules or overinterpreting it.
It doesn't hurt that the obvious highlight of the season--the nuke scene in episode 8--was wildly overanalyzed by lots of people when it could easily be summed up with "BOB is just the evil that men do."
I think another thing that helped me lose the plot on symbolism in movies in general had to do with Mulholland Dr. when I read a super-convoluted thread about how some super important clue was hidden in the FONT on the sign outside the apartment where Betty and Camilla find the dead body in the bed. I also asked what the symbolism of Billy Ray Cyrus' mullet was and I think I got a serious answer. This was on the IMDb board.
