I like that Lois has fallen for Clark Kent, knowing nothing about his secret.
I like the younger Kents, and that Jonathan dies before he becomes Superman (the movies did that too of course). Jonathan taught him how to be a man, but nobody can teach him how to be a Superman. The closest Supes should have to father figure is Jor El's program.
The meteor shower was a good idea, although the show did seriously go overboard with the amount of K-freaks.
I really dig what they've done with Doomsday so far, especially his origin as Zod's creation.
Braniac being from Krypton. The animated series did this too. I always liked it better than the Collector from Colu story.
I think they've actually implied that Clark worries about what he might accidentally do a woman if he attempts sex.
