with extended gun (so called mech tech  )

1. The Ferrari 458 is named Dino (sucky name ) instead of Mirage and speaks with an Italian accent and didn't show any ability to go invisible.

2. The Autobot Mercedes Benz is named Q instead of Wheeljack and speak with an English accent. He gave Sam the Cybertronian weapon instead of Brains.

3. Sentinal Prime's attack seems to be very powerful to even cause Ironhide to rust to death (whoa..!) which we don't see in other robot's death scene.

4. Brains transform in to a laptop.

5. The gigantic worm is Shockwave's pet and carries him around....cool

6. Sam being thrown out of Bumblebee when they get rammed by the Dreads. Bee transformed then pull Sam back in to the car seat safely yet Sam still continue to squeal like a girl....priceless scene.

7. Laserbeak can speak and transform/disguise himself in to various forms. (truly show off his spy capability)

8. The Wreckers are always in mechanize vehicle mode throughout the movie. No normal Nascar vehicle mode.

9. There are a lot of unnamed Decepticons (saw a cool garbage truck one) all around the world but there only 9 Autobots in Washington DC ? I'm wondering what will happen to all of them after this and how long will it take the Autobots to sniff them all out.

10. Barricade is still alive (briefly... )

12. Wonder what happen to Sam's parents.

14. All the Decepticons (in W.DC) dies in the end including Megatron & SS. Don't know how they are going to continue if they ever decide go on with TF4 (Rodimus/Galvatron maybe ?)
