I thought Voyager's mission was to eventually make it home?!
18 February 2015 | by See all my reviews

I read through another review of this episode and I really had to agree. If Voyager is lost in the Delta Quadrant and they are trying to get back home, WHY do they keep taking all these unnecessary side trips? And, why do they keep going off on rescue missions when they are in need of rescue themselves?! Here in "Macrocosm" the Captain and Neelix are off on some unneeded diplomatic mission and the ship goes off on a rescue mission that, not surprisingly, just about destroys the ship! The end result--the ship gets infected with some weird virus that assumes HUGE sizes and is awfully difficult to destroy.

So what's to like about this one? Well, there is a lot of slime and we do get to see Janeway actually killing something and acting tough (both are VERY rare). Otherwise, the show just doesn't make a lot of sense AND the aliens they negotiate with are among the most annoying in Trek history. Not terrible but certainly far from good.
