As usual, a slam-bang season finale. From the screenshots released by The CW, I predicted that Martian Manhunter and Lionel Luthor would join forces with Clark. I also predicted that Chloe's Krypto-power would be to sacrifice herself to save a Lois who'd bled out.
I didn't predict that a car bomb would kill Lana, that Lex apparently wouldn't be behind it, or that the phantom would turn itself into a Bizarro clone of Clark.
Great stuff leading into the next and final season. I wonder if Lana's and Chloe's deaths will stick. You never know with Smallville.
