I just saw it a couple hours ago. I found it disappointing. There were no glaring problems, it was just too predictable and recycled. Well, the whole Kolarus III scene was stupid. Why would starfleet need a SUV like that when you have a perfectly good shuttlecraft that will go anywhere you need to go, at a much better speed. Dumb. Oh yeah, lets not worry about the natives seeing a bunch of aliens take off in a flying ship. Prime Directi-huh?
They could have spent a little more time explaining how one guy goes from downtrodden slave to leader of the Romulan Empire. hmm.
Then the long drawn out part where they first arrive at Romulus, the guy wants to chit-chat, wants Picard to like him, even his underlings are complaining, quit talking, let's just start fighting.
Data. B4. good grief.
Star Trek needs new writers badly.
