After a long wait, ‘The Walking Dead’ returned last night. I like the show as much as I’ve liked any show since ‘LOST’ (but there will never be another ‘LOST’), but I was a bit let down by the Season Three premier. A lotta zombie killing, which is swell, but it was mostly a “setup” episode. That’s fine and necessary – but in a season premier, I usually expect something totally out of left field.
