Mhm....not sure what to make of that Dr. Who stuff yet. I'll give it another try now (another episode). Same with Game of Thrones.
What you have to realise is that Doctor Who was something that started in the 60's & was likely something my (& GOD's) dad watched. This was passed on to their offspring as the series continued & evolved. The BBC then screwed it up right royally & it sort of "died" really but still had a cult following. It was re-booted in 2005 with all modern effects & so on, but still the same premise. I think I might move these Doctor Who posts the Doctor Who thread where it can be expanded on a bit.
Everyone has their favourite doctor & also their favourite baddies. My suggestion to you is to try searching for a classic episode from each Doctor (he Regenerates into a different person every few years).
Youtube may have them. Pick a Doctor you like (Tom Baker is still one of the best) & try a story out.
Have to agree with Steve, there is an awful lot of history that comes with Dr. Who. Enemies like the Daleks and Cybermen are something we have grown up with an therfore have extra meaning when they reappeared in the reboots. The other thing to get your head round is the role of the Master, and also the importance of the Time War. Also, there's a lot techno-babble in many episodes that can get in the way of important aspects of the plot. Recently, I've started reading the episode summary on Wikipedia after watching an episode as it help to place the story line in the context of the overall series (there's often a thread running through a series such as "Bad Wolf"). Maybe if you watch 1 series and then read each episode review, it might fall into place. Def check out Steve's links.
