STAR TREK- worst movie EVER

[Paralus]

.....even if the script for the first episode we see them in was stolen from that movie about an American destroyer v U-Boat, with Curt Jurgens as the U-boat Captain....)

And a good episode it was - even if using (the later - introduced in Journey to Babel) Sarek for the the Romulan.

Is anyone anal enough, like me, to own the books that trace all the plot faults/goofs?

Yes. No more need be said.

.....does anyone remember the great episode where this was done with a plot-line about an 'evil' piratical crew in an alternate universe?

Mirror, Mirror if I recall. A neat plotline that.

Do you recall the episode where a former Starfleet captian was the Roman emporer on a planet where Rome, seemingly, never fell? Telecast galdiatorial games et al? Not to mention Romulan society....

You need to address Hydaspes "old Man".
