NOT a good adaptation of the comic, or show. Just a bad movie.

Rating: 5/10 (7 July 2007)

Top 10 reasons to hate this movie:
1. Too much product placement. But I must digress; the Transformers going into Warrior-Mode (Bipedal movement) broke up the 2 hour-long car commercial.
2. Poor acting. "THIS IS A DEFCON-5 SITUATION!" "You need to move past Fourier transforms and start thinking quantum mechanics." "What's crackin', little bitches?"
3. I was promised good Transformer character development and continuity with G1 and beyond. Nope. Bumblebee was supposed to die. He was cute, cuddly, and pathetic, but he never died. Optimus Prime was supposed to die. Scorponok was portrayed as a sneaky, insect-like, insidious alien. 20 years of transformer character and background story chucked out the window.
4. The only decepticon that seemed truly evil was Megatron. The decepticons were purely tools for moving along the plot; they were bereft of any true evil.
5. The Transformers look terrible. "Realism" isn't a valid excuse as they look like a costumed man covered in adhesive rolled around in a junkyard as metal scraps stuck to him. They are too cluttered. Optimus Prime has eyelids. Why?
6. Armageddon music in random scenes. WTF?
7. Optimus gets his ass handed to him by Megatron. Massive letdown to audiences.
8. Hugo Weaving was the voice of megatron. But he wasn't. It was covered by bass here, treble there, digital modification and normalizing. What was left was a voice that modulated, but lost all emotion, whether evil or infuriated. See: V for Vendetta. See also: The Matrix.
9. Human able to single-handedly bring down Decepticon with the use of small-arms. This notion is silly.
10. Megatron appearing to be a mass of twisted aluminum foil that turns into a random alien jet. What about a big cannon? Is that just not cool enough?
The original Transformers story was excellent, as characters were developed properly, there was good focus on each transformer and there was a wealth of comedy, tragedy, betrayal, and action. This movie does not offer any of this, besides a little comedy and too much action.
Some scenes were rather enjoyable, such as Starscream's dogfight with earth pilots, the scene with the mountain dew bot (the Cadillac SUV was a little over the top), the final fight sequence.
Its a good movie if you have no love for G1 and just want to see some brainless violence and explosions. If you liked Armageddon, Pearl Harbor, and The Rock, this movie deliver on the same mediocre level.
I hate you, Michael Bay.
