Let me be clear: I do like TOS in the context of the 60's, but I still prefer more recent Star Trek, except in this.
First glimpse of the Romulans and they really are VERY Roman. And that is something I want to see in a space context, because I'm used to warlike races that are more vicious or fierce or war-obsessed than noble. Most of the evil empires I've seen are German-based, some America-based, a few Japan-based. And of course, Egypt based.
I could use a change.
Also I like Romans.
Of course, it doesn't hurt that the commander reminds me vaguely of Laurence Olivier in Spartacus. Crassus was a MARVELOUS opponent.
