I found myself getting very annoyed at the plot last night while watching it, especially regarding the Nesbitt character - ignoring the fact that he really shouldnt be on the mission in the first place! ...seeing it is so close to where his wife died! would anybody in their right mind let him go on a vital mission to the sub that she was a member of the crew?
Also why was there no mention or check to see if there was a breathable atmosphere on the lost sub? ...Surely seeing the cabin wasnt flooded it isnt too much of a leap to wonder if the crew had exhausted the oxygen supply before they died? ...it does feel paper thin and written in a hurry to me tbh
I did really enjoy the new Sherlock, just a shame they only did 3 episodes in this series
