So, I just played the ME3 Extended Cut. Surprisingly, I enjoyed it. A lot, actually. That might surprise some people, given the alternate ending I wrote and how it effectively railed against the original conclusions, but let me explain.
My problem with the original ending wasn't that it didn't make sense, because a lot of the Mass Effect universe doesn't make sense. Biotics, Indoctrination, Element Zero, Asari physiology and most of the tech and lore of Mass Effect is quite ridiculous, but the writers do a damn good job of covering that up and making you believe. So I'm willing to go along with a silly concept as long as it's executed proper
