Due to problems beyond my control, I could only see the episode from the funeral scene onwards. I have to say, I was somewhat impressed by just that little bit I saw.
The culture of the Kandorians was represented with the funeral. It was fascinating and different enough without looking cheesy. The music chosen for it was even better. The funeral also made me wonder, just how many Kandorians are left? Surely a guy as smart as Zod would know you need a certain controlled population if you would want to continue the race.
Then came Clark finally doing something ballsy and fried the tower. You could tell on Zod's face that a line had been crossed by young Kal-El.
Didn't see anything about the gem K-rock and that may have been a good thing I am guessing.
