Yeah, I understand that, but it's still a bit of a stretch. I mean, I totally understand that they needed some sort of timeline altering plot to allow the series to go in it's own direction. It just seemed odd to have a mining vessel. Why not just take it a step further and make it a disgruntled Romulan admiral that had the exact same story as Nero as well as an advanced warship... I mean for all intents and purposes it would be the same thing. I haven't read the prequel comic because I expect movies to stand on their own, it just seemed like such an odd choice.
In the end, it's one of those things I just smile and nod for. After all, it IS Star Trek.
