I am old enough to remember the Transformers series of the 80's. Yes it was cheesy, but I loved it.
The rebooted live-action has been hit-and-miss with me, and sadly this is more miss than hit.
The plot is that the Autobots discover a dead leader on the moon, who turns out to be more than meets the eye, and the Decepticons attack in order to bring Cybertron to Earth and enslave humanity.
If you are a fan of the previous two films, you will love this; transforming robots, big guns, bigger explosions, lot of running around, some very hot women, a major crisis... you get the idea.
However, for me, this movie suffers with the same problems at Revenge of The Fallen - what plot there is (and it is limited), makes absolutely no sense whatsoever.
If Sentinel was defecting to the Decepticons at the beginning of the movie, why did they shoot him down and lose all that cool technology?
Optimus and the Autobots spend large chunks of this movie, not being where they should be and thus making a bad situation worse... but with no explanation.
When they do turn up, it is evident that the Autobots have been to the General Custer school of military tactics - they allow themselves to be divided, with no attack co-ordination.
Why do the bad guys have to tell their captives the one weak spot in their whole plan? I mean come on!
Ultimately, the action pieces are fantastic and the CGI is near perfect... but the script is full of holes that made me feel like I had wasted my time.
