I recently watched the second season of Fortitude via Amazon Prime streaming. It originally aired earlier this year.
as I did a few months back). Obviously you expect that from the second season of any show, but I thought it was particularly striking here. Almost all the central characters are back (even a couple that didn't look very healthy at the end of season one). The big mystery from season one continues to have effects into season two. Political intrigue, personal relationship drama, and unexplained mysterious deaths are everywhere. And the landscape is still snow, snow, snow with the occasional ice and freezing-cold water mixed in for variety.
None of that is bad, since I liked season one and more of the same is pretty much what I signed up for when I hit play on season two. I will say, though, that this season felt weaker, as if it was a less intense version of the first. Some of that is familiarity with the setting and actors, taking the shine of discovery off, but I also think the writing may have been struggling a bit. It's not easy to follow up success, and I think that shows here.
Having said that, it's still a fun ride through the second season. Some of the new characters are fairly weak - the shaman in particular - but they still have depth. No one is all good or all bad, and there's plenty of misdirection about motivations to keep things interesting. Disturbing and mysterious deaths show up regularly, keeping the suspense going. I also thought the family drama of the Lennox family on the personal relationship side of things was a good addition.
It's certainly very possible that we'll see more Fortitude at some point. There's plenty of plot threads left dangling in terms of the big mystery. While a few characters seem pretty well gone, there are plenty left to keep going. If the powers-that-be decide that they want more tension in the ice and snow, there's room for it.
