Its hard for me to place Fringe as its somewhat a show of extremes.
For the first 4 seasons it was mostly very very good, just occasionally just a bit too silly or inconsistent.
It was essentially a modern xfiles, but with a strong voice of its own. A small group investigating strange events - freaks of science or other problems. Many ultimately the result of one of the protagonists actions a long time ago.
Over the first seasons it went up and down, but was never a chore to watch. The concepts were normally interesting, the characters strong, and a healthy dose of humor now and again too.
Then the last season came and with it drastic change. While drastic change isnt always bad - far from it - in this case it was. It somehow jumped from fresh sci-fi concepts each week to fighting the most crazily cliché villains possible in a sci-fi. (emotionless nazis forming a oppressive regime). It then became all about fighting for "freedom" from the oppressive overlords. *yawn*
It only really recovered in the last episode, which thankfully covered pretty much everything a last episode should be. It revisited a lot without montages, it had characters acting their best, and it resolved what needed to be.
So when writing this review I am trying to average those highs and lows.
