Looking back at it, season 5 was a huge waste of potential. The first three episodes were incredible, the next three were ok, but not great and the last 4 were bad. The pacing was all over the place past episode three and the fight scenes lacked tension. Plotlines were picked up and dropped for no reason aside from, at most, small cameos in the final fight (which was bad). Worst of all is the fact that Jack seemingly did not care that his allies and friends were erased from time, he doesn't even think about them.
