The third-season premiere of Revenge (Sunday, 8 p.m., ABC/Ch. 4) spends much of the hour erasing what happened in Season 2.
This is a good thing.
Season 1 of "Revenge" was pretty darn good. "Season 2" was a bit of a trainwreck at times. It was more than a bit of a train wreck at other times.
The set-up for the series was that Emily (Emily VanCamp) showed up in the Hamptons looking for - you guessed it! - revenge. Her father had been framed for complicity in a terrorist attack that brought down a passenger jet, and she was out to get the Grayson family, who were behind it.<
