Episode cast overview:


While the Enterprise makes an astronomical study of a 87 million year old rogue comet, it discovers a ship-like construction, possibly the nucleus, which contains alien artifacts constituting the 'archive' of an Ancient culture. From then on the aliens take over, 'possessing' Data's positronic network to give him several of their personalities, including the talkative Ehad and the feared queen Musaka. Alas they also transform matter and even genetics aboard, so as to turn the ship into a city their style. Picard resolves to stop that by understanding and playing the key alien characters. Written by KGF Vissers

Counselor Deanna Troi: How's it going, Data?
Lt. Cmdr. Data: I have finished. The dimensions are accurate to within 1.3%.
Counselor Deanna Troi: I'm sure they are.
Counselor Deanna Troi: Data, you obviously don't have a problem with realism. But, you're here to work on your imagination. Maybe you should try something a little more... abstract. Here.

The worst TNG episode
11 May 2008 | by (Norway) – See all my reviews

I have been watching TNG again (or so I thought, but I found out I had only seen about 50%). I'm now at season 7 and just saw the episode "Masks". And what a torture.

I know that many complain about Sub Rosa but this episode sinks lower. The writing was so bad that I had look away at times and the plot was just plain stupid. Why would someone create a station like that in space and to what purpose? But the worst thing with this episode is the stupidity of Picard. He is supposed to have studied ancient cultures but he does not get that it is the moon that can put the sun to sleep. Even the sign they find looks like a moon and still he does not understand anything. It is very bad when the viewer is 25 min. ahead of the "intelligent" Picard.
