Ok, first of all Fonzie jumped the shark when they all went on vacation in California, it was nowhere near Lake Michigan.
Second, the finale was a huge copout. Any plot line they couldn't figure out a logical resolution to, "God did it."
I have no problem with the throwing in the idea of some higher power having a hand in things. And its not that every single plot point needs to be answered completely and with nothing left to ponder. But there's a difference between hinting at a divine explanation, and just plain sloppy writing, which this was.
Although there were still some interesting moments, in a way some stories did get resolved. I've certainly seen worse series finales. What really got to me was the old-school Centurions duking it out with the new models. That was frakking awesome, as was the old theme song playing as the ships headed into the sun.
"There are those who believe that life here began out there..."
