Did I like the season finale of "A Game of Thrones"?  Not really.  Do I respect the television writers for finishing what Martin refuses to finish?  Of course, I do.  Did they make quite a few mistakes?  Yup.

The writers and the studio didn't really do justice to, what was, one of the most popular television shows of all time.  Their first mistake was, I believe... doing the mini-movie episodes.  I thought they're should have been more episodes to create more tension and conflict- I'm talking 26 to 30 episodes a season.  Think I'm crazy?  Star Trek- Deep Space Nine, season 5 has 26 episodes... 26!  In the last season of G.O.T. there were 6.  6!  The Battle at Winterfell should have been the last episode in season 7, and they could have broken it up into two, one hour episodes.  Secondly, many, and I mean most, of the character arcs of each character were not built up to a satisfying conclusion.  Did you like where Arya ended up?  Me neither.  What about Jon Snow, or Cersei, or Jaime, or daernerys, or Sansa, or Bran?  Lame.  Jon Snow should've been beheaded by the Unsully just like his father, and thereby providing a cyclical experience for the audience.  If you start your story out with a beheading, you might wanna think about ending it with a beheading.  Daenerys going bat-shit-nutters and slaughtering everyone in King's Landing was done too quickly.  We only got a few seconds of her brooding rumination before she decided to be become a mass-murderer.  I hated the way Cersei and Jaime went out.  Are we now supposed to believe that they've been redeemed by their love?  Lame.  My brother had the idea for Arya to have killed Cersei- wearing one of her faces, which would've been much cooler than what happened.  And lastly, the king of the Seven Kingdoms... woops, Six Kingdoms is the lamest character in the entire show- Bran; who does nothing but pontificate and prophesize about what?... really?  Nothin'.

Lame.

Now, with all that said there is only one person that any and all should blame.  And that person is George R.R. Martin.  The writers of the show were told to do what they did by the P.T.B. who held the money.  They cannot be held accountable for having to do what they were told to do.  However, Mr. Martin- a great writer- did something he should be ashamed of... he did NOT finish what he started.  You're a writer.  Your job is to write.  You get paid handsomely, and you can't even finish what has become one of the most beloved fantasy series in the entire genre.  There's no excuse for this.  And every quibble and complaint (including my own) should be heaped not upon the doorstep of HBO or the writers or the producers, but upon Mr. Martin himself.  For shame, Mr. Martin... for shame.
