I thought it was great. I really liked the little homage to Superman: The Movie when Clark is in the chamber in the Fortress of Solitude. In case you missed it, you can see one of the shots of a person floating at the time Krypton's destruction from the 1978 film among the images for a brief moment. I wouldn't be surprised if there were other brief clips shown that I didn't catch.
So many cool things were introduced: The realization of the Fortress of Solitude, The Phantom Zone, the concept of Zod.
And I totally agree about Lex giving a sense of dread whenever he appears on screen. Very cool aspect of the series now.
My only caveat is Clark losing his powers...again. This has been overdone, IMO, and really it's rather dumb. But that aside, good things ahead.
