ost_uid0]I have the Star Trek Communicator's special on time travel episodes stashed somewhere in my drawer. There are TOO many time travel episodes to count with my fingers. And yes, I agree that the Big Reset Button plot device is a MAJOR cop-out, because it means that the writers can get away with anything without consequence!
Star Trek is not the only series which does this. "The Locket" from Farscape, for example, is one of the biggest reset button episodes I have [i
