I mean, I still don't get this insistence that there is some long history established previously between Picard and the Romulans that's begging to be explored. I don't see it, Klingons, Cardassians, Borg, yeah, but aside from a few key Romulans he interacted with and obviously Nemesis I'm not seeing it. I guess, the angle they could take is after the events of Nemesis this relationship got built up given the team-up at the end of the film to fight Shinzon, which made Romulus's destruction important to him. It's all conjecture and back story exposition at that point and not really jumping off from anything established in TNG to any deep degree.
However, if they're using this opportunity to flesh out the Romulans a bit better that would be welcome. Aside from maybe one defector they're still probably the most "stereotypically" portrayed races in the franchise I guess.
Bring back Tasha's daughter. I'm also going to be annoyed if we get very few guest appearances from other TNG alumni that may be interested.
