My wife and I recently watched season two. We had not seen season one previously and won't be going back to watch it now. We really like Alone and were thinking this would be something similar.
The first couple episodes were enjoyable enough to get us in, but the further in we got the more this show felt like the producers were just making it up as it went along, and ultimately it felt like they just decided to end it abruptly. Maybe they ran out of budget, who knows.
What I do know is that it was extremely disappointing to watch an endurance competition suddenly be turned into a foot race. It should definitely not be called Outlast if the objective is to get to a finish line first.
