As hard as it was to believe the possibility of a ship with time barriers, where characters pass through an find themselves in the same place at different times, I still thought it was fun. I agree, with some time and thought, it could have been great. Chakotay is the natural foil here because of his varying roles, from Maquis terrorist threat, to kindly first officer to Janeway. What we do get to see are glimpses of all seven seasons, used in a creative way.
