I am no Michael Bay fan, in fact, I consider him a director who cannot make a movie without an onslaught of eye raping visual effects, which is the only reason why I rented this movie.
Naturally, I got what I was looking for, but not an iota more, which only confirms my opinion of Bay.
The concept isn't new -- an alien race whose world was destroyed faces off on our planet -- and works considerably well, even though there are lingering questions about how the robots avoided detection for so long.
The execution is good, meaning that the visual effects are quite awesome, but the script is quite light too, leaving the actors to, at times, utter sentences that make your eyes roll toward the ceiling.
Shia LaBeouf, a decent actor for what I've seen so far, can't be blamed for signing up to play a role in a multimillion dollar franchise with the potential to propel his fame worldwide, but I doubt he will be remembered for this role.
Even less can be said of Megan Fox, who was utterly unknown before this role and whose only credit seems to be her beauty. But this being a Michael Bay movie, what can you expect.
In the end, the visual effects, which as I said are pretty powerful, are the real protagonists here, but I wouldn't put them in the same league as those from Star Wars or The Lord of the Rings.
See it only if you like visual dazzle and you can stomach a bland mix of nothing else, otherwise skip it.
