Living Witness (*****)
Some good fun is had with an alternate and "evil" version of the Voyager crew, but rather than just being a "fun" alternate reality story such as the various Mirror Universe episodes, Living Witness
uses this fun beginning to tell a good story about the problem of revisionist history. This is probably my favourite Voyager episode so far.
There is the issue about Dr Shmully apparently having a back-up even though this doesn't fit with continuity, but was the episode good enough to justify this contrivance? I think so, and I'm going to give it my Official GodBen Seal of Approval
