If you're a car, I suggest you keep the fuck away from Michael Bay. He destroyed about two dozen “future cars” in this movie, all of which looked generally like Chrysler 300s. In fact, pretty much all cars look like the Chrysler 300, Dodge Magnum, or Dodge Charger in the future.
In any case, this was a pretty good storyline by Bay's standards, had his usual requisite action and chase scenes, and was generally entertaining to watch. Going in, I expected this movie to be a Matrix ripoff, but was pleasantly suprised to see how it managed to avoid any really obvious comparisons. It's actually a fairly original screenplay, though the ending is predictably sappy, and there's an odd hole/plot device that is left unexplained. I won't spoil the film by getting too far into it.
It's also worth noting that this film is, apparently, Hollywood's version of political even-handedness, as it casts cloning (i.e. stem cell research) in a fairly negative and morally problematic light.
