Vox Sola

The show begins with the Kreetassans becoming VERY offended at something the humans did during their meeting. However, instead of telling everyone what offended them, they stomp off the ship and it seems like a first contact experience with these folks blew up in their faces...but why?! Well, another first contact experience occurs soon after this--and it goes even worse!! Some weird tentacled creature is hiding in the ship--and it soon grabs several crew members (including the Captain and Trip) and holds them captive. What the creature is, what its intentions are and the fates of the crew entangled within it are all uncertain. So, it's up to the Doctor, Reed and Hoshi to figure out what to do.

The episode is awfully good because it it such a weird and unusual creature and I appreciate that. Too often, the aliens all are bipedal humanoids, so having something 100% different is a great idea. Well worth seeing.
