I love all the cast on this show. They are all talented beyond anything. But and it's a big but, the show suffers from an over emotional investment into psychodrama. Emma should not be susceptible to the breakdowns she exhibits and neither should any other members of the cast. It completely justifies questioning, seriously, why anyone of these people were chosen for this mission. Mental and physical stability and fitness are supreme in these arduous circumstances and frankly that does not come through. Many many many depictions of emotional struggles repeated exactly after one view point. It becomes tiring and detracts from the task at hand. There is a question of resilience that covers everyone on the crew members and if this question becomes central to our perception of the show, then it will not go down well.j
