Seasons 1-5 were fantastic - 2 in particular - for their production values, acting, but what made it stand out was the plot. The moral quandaries, questions asked, survival strategies, emotional fall-out, PTSD, what is worth dying for, etc etc, were what made the show so compelling. This season.... just outright sucked. Maintained the same level of production values and acting but it was like they had no plot to work with, especially in the second half.
Thinking if next season is the same quality, I'll give up. They've said they can see it going on 'forever', so I'm certainly not committed. They've given us a way out, actually.
