My advice would be to put your expectations and prejudices behind and just watch and enjoy. Yes, there are some episodes that are mediocre, some that are ho-hum, but some of them are Trek at its best. Mostly, enjoy.
I've been contemplating a rewatch myself!
I concur. In many ways, Voyager was the spirit of Trek at it's best. Episodes that I especially enjoyed:
Dark Frontier (my absolute fave)
Bride of Chaotica
Barge of the Dead
Someone to Watch Over Me
Real treats imo.
