A lot of my sentiments about this finale are missed opportunities. They had 2 hours to really put a lot in there, but spun their wheels and wasted a lot of it to be honest. There was also a lot of hype leading up to it. So while we should have all expected the same tripe we usually get from Smallville, this finale seemed special, like they were going to really ramp it up and give the fans what they wanted. However, it did not deliver. It is sad to see the series go out like that, but it is what it is. I'll write up a more lengthy grade post later.
Leaning toward a Below Average right now, but I am going to give the finale a second chance, watch it again tomorrow, and then grade it upon second viewing.
