I feel like we needed a TNG movie with Romulans as the main villain properly used unlike Nemesis and ST9, which, yes, had Romulan villians, but neither of them (Shinzon and Nero) were acting within the confines of the Romulan Star Empire but were, essentially, renegades. Speaking of Nero, why did Starfleet never try to contact the Romulan Government to find out more about Nero (to the extent that they had a way to contact them -but they clearly knew of the Romulans) There are some well-regarded Romulan-centric episodes of Star Trek TNG and DS9 that could have made for more interesting movies (i.e. Redemption- which had both Romulans AND Klingons, Unification, Inter Arnim Silent Leges) IMHO.
