Star Trek

You're talking about Before and After correct?

well, that never really happened. In that episode Kes started jumping backwards becuse she was infected with radiation from the unexploded torpedo. But Kes left before that happned, so she was never infected with the radiation that cause her backwasrds jumps. So she never knew about the Krenim, and never warned voyager about them.

I don't think that the equinox crew DESERVED to have their traumatic times erased. They tortured hundreds of innocent beings, they should live with that

that might be true

But they had similar survival situations before...none of them spanned a whole year of course but Deadlock for one. Voyager was beat to hell, almost destroyed, they were ready to abandon ship.

Year of Hell gets my vote as the best Star Trek ever. I love episodes revolving around reality/time being altered.

I hated Year In Hell. I did not enjoy seeing the ship torn to pieces and watching her crew splinter and break. Terrible terrible. The premise was a good one though I would have rather seen it happen to say....Kirk and that crew. That would have been hilarious!

In my mind, this is because Voyager had better technology so it was easier and quicker to make their repairs LOL

Look at it this way; if someone were to change the course of history, do you think we would have any memories of those changes?   Star Trek was quite consistent with the idea that tampering with the timeline(s) would usually mean that only the perpetrators of those historical changes would recall anything of the old/previous timeline.  In the Year of Hell, that temporal ship was annihilating civilizations from time, the premise was that the annihilation of the temporal ship itself would cancel out any changes made by its crew; thus the Voyager crew remembers nothing as Captain Janeway ordered the temporal shields be deactivated prior to the temporal ship being destroyed.    

In TNG, like it has been mentioned in “Yesterday’s Enterprise” only Guinan retained any sense/intuition of the changes in the timeline, the rest of the crew was absolutely oblivious.

In DS9, I think it was in season 4 “ascension”, were a Bajoran poet aboard an 200/300 year old light ship suddenly appears through the wormhole, he contends that he is the Emissary and Sisko backs down until the poet instigates the reinstatement of several backwards traditions and superstitions.  Sisko and the Bajoran poet go into the wormhole and the Prophets return the poet to his original time, however they somehow make it so that everybody remembers an incomplete poem written by the poet, only now he went back and finished it.

Needless to say there have been many instances when a crew has tampered with the timeline, in some cases only that crew remembers the changes, in others no one.
