Review of The Great Fabricator

I truly don't understand how writers can take such a clever, heartfelt, beautifully-crafted show and abandon all pretenses of logic or narrative satisfaction in favor of suddenly wanting to write an action flick. Major story beats happen for essentially no reason, and characters seem like they were transported into a completely different show. I can almost see what they were going for, but the way everything was executed and the arbitrary character deaths left much to be desired. I do not see how this episode contributes at all to the themes of the show, outside of the obvious superficial level. Very disappointed by the conclusion of what was becoming one of my favorite shows in recent memory.
