Adama, no contest
Which one???
My impression of the new BGS Adama has never been very high.
Early on there were indications that he was rather a flunky and operated his vessel and crew similarly. When the War happened, his ship was out of range (ie., out doing flunky stuff that it shouldn’t have been doing) and that was the only reason it survived. The ‘leadership’ of the surviving military was hoisted on Adama by default.
He always seemed more interested in taking care of the few close to him than in the overall security of the survivors.
I noticed the Prez had a board that had the number of survivors. It kept dwindling from around 50k to 45k to 40k. The final number I recall was something like 39k. That was a relatively high loss percentage.
