Transformers.......

"I am Optimus Prime and i am sending this message to all surviving autobots taking refuge among the stars. We are here. We are waiting"

finally, i hv watched "Transformers" today....my comments? yeah, a lil boring initially and it gets better when the action starts....except i hv few Qs i wish to directly ask the Director. who was it again? Michael Bay? uh ok...you may find my Qs are rather er....W@#@$..but hey, i'm just being honest...heh heh...
1. Why would Sam shoved the cube into Megatron's chest instead of Prime's? I thot Prime asked Sam to do it the other way around.
2. Why "SAM" to run around to send the Cube to er..Military hands? why wudn't the other autobots do it?
3. The good team can't destroy the cube meh? Why must send to the human military team? to hide it? it won't end the story rite....
