I enjoy both, but yes I agree with you not all filler episodes are worth it. I do notice as I am watching Hawaii five o now, with long seasons that I skip both epsiodes and scenes within episodes I do watch. And I prefer not waiting a week between episodes and that does work better with short seasons, and as you say the story can be much more well written and handled when the focus can be put solely on that story.

I don't have any new shows on my radar either at the moment, but I am often bad at keeping up with what is coming. As with you I look forward to the return of shows: Victoria and Call the midwife are two such shows.
