It was alright. Nothing special. Then again, I'm not a big Zombie fan.
The Lana "cameo" didn't bother me, but I did like was it represented. He took her out of his wallet and threw her picture in a book. It was suggestive to me of fully moving on (about friggin time too).
What was with the swords? Very Highlander-ish.
Also, thanks CW for spoiling the episode. There was no hint of a Zod connection until the very end, yet they put it in their episode description.
