The Day That Wasn't was frustrating because all the character and plot advancements that were made got undone (Except for Five). I think there's a time travel bug there - shouldn't there be 2 Fives at the start of the say, the original and the one that came back?
The time travel as a whole was all over the map as far as how it works.
Didn't like that Luther got beat up. I mean if Hazel had been made superhuman by the Commission, they should have said that up front.
