I actually squealed in delight when Lois figured out that Clark was the Blur. And the ending! I love that solution, it was very fitting to the themes of the show and I loved that Zod was defeated because he gave his people powers but he hadn't yet fully realized what that would mean.
And Clark's inspiration during the fight!
And more Lois, who is awesome.
Plus, the cameos from the other superheroes were fun. Love seeing Michael Shanks, always.
Overall, splendid and I'm really looking forward to next season (Lois knows, you guys!).
My only disappointment is that Tess might (MIGHT!) be dead. I love that crazy lady. Otherwise, I think this is the best finale ever.
Oh, and to catch up on previous weeks - disappointed in the episode that killed off two awesome women (White Queen and Faora); loved the episode with Martha Kent as Red Queen plus Lois and Perry White working together.
