Trekmovie has a lengthy review; what interested me most were the reveals of the plot:
This is one of those things that can be either really good or really bad. On the upside, the movie's alternate universe does tie directly into the 'regular' Trekverse, and we might finally get the decent Romulan story that Nemesis wasn't (for one thing, the "Unification" arc is finally followed up on, in a plausible way); on the other, from the (limited) recap it does look like the whole exploding-star subplot is a bit light and very much a cliché. Then again, the summary suggests this is just the setup for a plot device in the movie.The comic starts simply enough, as see in the previously released 5-page preview. It is Stardate 64333.4 (eight years after Star Trek Nemesis), somewhere in the Romulan Empire. We’re aboard a small mining vessel, captained by a young loyal Romulan by the name of Nero. Smooth of brow, clean of visage, we soon learn in the subsequent pages that this young Romulan is not known to the Senate, but represents the Mining Guild there.

"Countdown" takes us into what could be seen as a follow-up story to the Next Generation’s "Unification" two-parter, which established that eleven years before Nemesis (and nineteen years before the comic) Spock was on Romulus covertly trying to bring together the Romulans and the Vulcans. Now in the post-Nemesis era, Spock has finally become an official resident of Romulus, serving as Federation Ambassador to the Empire, and sitting in on their Senate meetings. He has recently discovered some disturbing information about the Hobus star which seems moving toward becoming a massive supernova. In a scene very akin to Jor El’s warnings in Superman The Movie, the scientists of Romulus shoot down Spock’s theory, especially when Spock reveals that he may have a plan, but it involves taking a rare and valuable Romulan mineral to, of all places, Vulcan. Understandably, this does not go over well, but Nero steps up to support Spock’s claims, having seen an explosion at the star firsthand. This leads to the start of what looks to be a friendship between the two, and an offer that Spock finds impossible to refuse. Hey, wait a minute — isn’t Nero supposed to be the villain in the Star Trek movie? In a classic Orci/Kurtzman twist, there appears much more than meets the eye for this Nero.

Nero’s actions throughout the story presented in Countdown are not at all what we might expect. Here he is sympathetic, and shows all the characteristics of a classic Trek hero
Thoughts? Keeping in mind that these comics are tie-ins and (AFAIK) not written by the movie's writer.
