I was entranced with the very first episode and now I can't wait for the next episode. The next episode for us now is Season 5 and if PBS continues the trend that won't occur until January 2015.
Maybe I need to move to the UK, where the next season will be broadcast in the fall of 2014. Or continue what we have done by donating to PBS to get the whole season early in the States.
