I have the same sort of feeling for other shows that have had either short runs or short seasons. Downton Abbey, despite running for six seasons, only has 52 episodes (and an upcoming movie) which is about the same as most American shows that run for two seasons. Yet each episode has much more impact for that very reason.
Game of Thrones will have a run of probably 73 episodes by the time that it is through with its eight seasons, thus giving it fewer episodes than many three season shows. Yet that very brevity gives each episode greater heft. There are no filler shows or reflective montages that we have to suffer through.
This formula has also worked well with the Marvel series on Netflix. Honestly, a few of them could have benefitted from having cut a few episodes from their 13 episode seasons. Still, the shorter seasons make it easier to justify watching a season in a week or less (which is usually how we roll).
I still like some of the more traditional length series. Currently, Agents of S.H.I.E.L.D. has demonstrated that it is up the challenge of providing quality episodes despite having to come up with 22 of them each season. It is truly impressive that the creative team behind it has been able to come up with such consistently well-executed shows that drive us to watch the next one (well, it took a season or so to get going, but then ...).
We are in amazing era of entertainment. As much as I love many shows and movies from the past, I feel blessed to be in a time when such amazing content comes from so many different places. Inevitably, that means that there will be some gems that I miss as well. Hopefully, they have shorter runs so I can catch up on them quickly.
