The ending of this season was perfect. Joel's decision to kill the fireflies was brutal but also very in character for Joel. He values Ellie over the rest of humanity because Ellie is the new reason he has to live. The music, editing and set design are all fantastic as always. Salt Lake City looked fantastic and was very distinct from the other cities we've seen so far. This conclusion is complex and raises a lot of questions as to whether or not Joel made the right decision or if it was a selfish decision that doomed the rest of humanity. This is one of the best episodes of television history.
