Not all that dissimilar from the finale of TNG, and if you hold the two side-by-side there is no contest whatsoever, but this is still a neat zipping-through-time episode that ends kinda-nicely, but not quite.
We see Kes at her death, then bouncing back to her conception, and she can’t get back into phase. Or something. Trust me, it makes total sense when you see it.
The Ocampan lifespan is a fascinating thing, to be sure, so any light shed on it is welcome. Also: possible futures are neato too. (See how Chakotay becomes captain!)
I didn’t like, though, how blase people seem to be about affecting the Temporal Prime Directive. Janeway seems very eager to know about the evil that lurks behind the next star system….but would Picard have done the same?
