Personally I loved this episode and I wasn't expecting "closure" as that would preclude the necessity of watching any more of the show.
Lots of questions left unanswered.....love the suspense. That's what is fun - not know what happens next. Not knowing where the bad guy went to. Who will kill the SOB? And how will he die? Or will he die? And what happens to the rest of the characters? Will they stay at the prison through next season? Or move on? Will they go to Woodbury?
Good stuff - and I can easily wait. Time flies anyway.
New season of "Mad Men" starts very soon.
