I liked the long arcs when there was suitable material. I think TCW needed more one off episodes peppered in like in older seasons. I think the bigger issue with the long arcs is they made the season feel so much sorter because it felt like far less was covered unlike in earlier seasons where we we're moving quickly through all kinds of topics and settings. On the otherhand I think the arc format would have slowly made TCW more linear. It seems like TCW was getting more that way as it was starting to wind down. I believe Brent Friedman recently said TCW would have ended in season 8.
