It's time to welcome Dollhouse, Heroes and Smallville back to the TV sked. Will Echo's adventures live up to the promise of last season's finale and "Epitaph One"? Can Heroes turn things around in year four? Will Tom Welling look good wearing an "S" on his chest?? It's time for some answers, people.
Plus, FlashForward debuts on ABC and Warehouse 13 ends it first season on Syfy. Read on for this week's TV picks and video previews.
Heroes, "Orientation" – Circus freaks! Lesbians! Hiro on his deathbed! None of the promised storylines for season four make me want to start watching Heroes again but, surprisingly, NBC's intriguing preview video for tonight's premiere is having the opposite effect. Watch it after the jump. (Monday, 8 p.m. on NBC.)
