Vorik starts going through Pon Farr and it causes problems.
This is a fun episode with memorable character moments.
The plot is silly at times with a tone that varies from dramatic to humorous in various scenes. I like the scenes of analysis conducted by The Doctor and Tuvok on the Pon Farr in this context. Tuvok's dialogue in particular that explains the situation is plausible and delivered well by Tim Russ.
I also love the concept of The Doctor "pimping out" a female hologram for the sake of medical science and the humour derived from The Doctor's fascination with the subject.
A big part of the story is B'Elenna's condition and the involvement of Tom Paris. I like the their scenes together and how they impact the overarching Voyager narrative, but the writers include way too much explanatory dialogue. There are so many interactions between the two that I think would have worked better if they were done more visually, with minimal dialogue. Why does Tom have to constantly explain himself? For me it kills their chemistry. The same happens prior to an action scene towards the end, but this time it's Tuvok explaining everything.
For me Robert Picardo and Tim Russ give the most enjoyable performances. Roxann Dawson and Robert Duncan McNeill are also great, making the best of the material written for their characters. Alexander Enberg is okay as Vorik, but strays over the top in certain moments.
Visually it's good, particularly the during the more physical scenes between various actors. Star Trek show-runners love a cave, so as you would expect the set design and action is technically well done in these scenes.
It's a 6.5/10 for me but I round upwards.
