This is obviously a terrible episode... but I frickin love it. It's one of my absolute favourites, in fact.
Firstly, it's a bottle episode and I have a massive soft spot for them (wish there'd been more). Secondly, as the review says, it provides probably the best opportunity for us to see how some of the crews relationships are and have been developing. It's just a fun episode that I always enjoy watching (even psycho Neelix and his paranoid belief that Kes is banging half the crew).
That being said, I've commented on (and even started) a few Twisted threads in the past regarding the fact that the only people who end up in the centre of the ship (Sandrines) are the bridge crew.
I mean, the whole point of the episode is that the anomaly is supposedly pushing everyone to the centre of the ship. Well, where are the rest of the crew? Yeah sure, it's obvious why they're not there (because they're not the stars of the show) but in-universe it would have been nice to have seen some of the hundred plus crew members turning up too. Just a handful.
When it's been discussed in the past, I've always posited the idea that the rest of the crew were the only ones with the balls to just carry on with their work..."Oh look, a weird anomaly coming towards me... meh whatever, I'll just ignore it and carry on fixing this plasma conduit." Meanwhile the bridge crew all ran away from the anomaly and cowered in a corner of the holodeck.
