I don't get why the UFO's are such a problem.
My view is that you have an incredible season of television that has nothing to do with extra terrestrial activity at it's core. Sure you have mentions to UFOs throughout the season, and as many have noted...it was a common discussion in the late 70s. But once you have an actual appearance of a UFO, that has such an impact on the storyline of the entire show....to me, that puts a sour on it all.
I'll give them the benefit of the doubt and see what happens in the finale....but it just doesn't sit right with me.
To play devil's advocate....what benefit came out of the inclusion of the UFO in such a profound way (other than, that's the way they wanted to tell the story)?
