This Week in TV is a weekly feature reviewing the best, worst and most interesting episodes of television from the past seven days. The plan is to cover a wide variety of shows, but not always the same ones each week, so let us know in the comments which ones you’d particularly like to read about. This week takes on a comic book theme, with The Flash heading back in time, Oliver Queen suffering an identity crisis in Arrow, and, um, SHIELD suffering an identity crisis in Agents Of SHIELD.
