Really don't like this one.
As you say in the review, why does Chakotay need to bugger off into space on his own to meditate? I mean, it's not as if Voyager can afford to just throw away shuttle-crafts you know. Go meditate in the holodeck on some peaceful beach you complete berk.
The episode is just tedious. The Klingon-lite Kazon are possibly the least interesting species in Trek. The only Kazon-heavy episodes I can stomach are the one where Seska is the focus or the one that introduced the Trabe (and briefly gave the Kazon a mildly interesting back-story).
Then we have Nog the Kazon. As you say, he even speaks like Nog so this is distracting (maybe not first time round but definitely on later viewings).
To be honest, this episode has all the things that I least like about Voyager. Chakotay spiritual mumbo-jumbo, the Kazon, and characters doing stupid things (like taking a shuttle-craft out into space so you can meditate).
Don't quote me, but this could be my absolute least favourite Voyager episode ever.
