I'm proclaiming it, right now. (Links will contain major spoilers...)
The only thing which currently gets my brain a-buzzing, my pulse a-racing, my geek heart a-pitter-pattering as much as the ASoIaF series, is Sherlock.
While I understand that for the quality of the series to remain so spectacularly high they can only produce three per season, IT'S NOT ENOUGH. Just like waiting for The Winds of Winter (or, T-Wow, as my geek friends and I like to call it), waiting for whatever will follow "The Reichenbach Fall" is equal parts excruciating and exciting, both mentally and emotionally.
Thankfully, the interwebs indulge my addiction, while constantly proving to me that there are other fans out there just as invested. Even more so.
While following up on every theory and explosion of fandom awesome regarding these series may not equate to the best use of time which could be spent being 'productive,' it does get those synapses firing in a way nothing else does.
It's certainly better than spending my days following celeb news on TMZ and Perez Hilton...
