i enjoyed it for a change - as it was one long set piece in two timeframes, done very well. the monochrome thing is a bit of a cliche, but it was essential here. i love the way that some viewers think monochrome = artsy
they were no more artsy than the rest of the episode, which did look visually stunning throughout. it was just a way of distinguishing the two time periods.
it was an immensely stupid plan though - when all it takes is a sound to send them back in their own direction.
the dialogue sucked as usual - repeating stuff we've already heard a million times to fill time - with the exception of the scenes with rick and morgan, comfortably the two best actors on the show.
