ONCE UPON A TIME
ABC, 8:00 p.m. ET
There have been so many good shows vying for attention on Sunday nights, this ABC series has sort of slid beneath the Best Bets radar – but it’s still on my weekly list of shows to record and watch. Season 2 has enriched, rather than diluted, the overall high concept of this fairy-tale-gone-sour series – and this year, with the evil Regina continuing to play with the hearts and dreams of those around her, things have gotten even nastier, thanks to a series of increasingly enlightening flashbacks.
