I voted 'Red-Blue Blur', only because I thought the Zod material was a bit weak and felt forced here. It's like they were trying to do too much in a single episode - I'd have save Zod for the second ep and gone from there.
The Clark/Chloe rift is long overdue, I just hope that they can come to terms before she may buy the farm and Clark has another death to feel guilty about (after all these years of dodging the bullet, I really think that the cute blonde's days are numbered this time, perhaps to serve the Bigger Picture). We'll see.
All in all, a better season premier than last year, IMO.
