I've watched this from the beginning, and was intrigued from the start -- the first two seasons were really good!

...then the 3rd Season came. What a huge disappointment! Sure, visually, it's very cinematic -- perhaps even too much so for TV -- but the dialogue became very distracting in its streaming of pithy little sound bites. I've been struggling for a while to come up with the right words to describe it: it's like streaming overly-dramatic one-liners together to make up a sentence. Terribly distracting!

Then there's the utter confusion, the warping of space/time that Einstein would've been proud of witnessing. That was always the initial hook of the series, through Will, but it took a whole new level this season -- enough to be just utterly confusing and, honestly, less fun.

So, while I've enjoyed the first couple seasons, and, have been struggling thru the last season, I see no other way for this series to end but by overproduction suicide: over-thinking it to death.
