there are multiple things in the movies that we dont notice till we've seen it a few dozen times and thats true for everyone after taking close looks at all of the movies, here are some cool things i noticed 2007 -BB car mode is always nice and clean but his car parts are always dingy in robot mode -sams recorded words dont match what he said when he first saw BB -when ironhide blows the s7 vehicle tires, ratchet has a gun on each hand -when bonecrusher transforms, his claw isnt already extended -blackout attacks sam twice but doesn't try to take the cube ROTF -camera crew in transport plain -sams cup keeps changing filling size at college party -when blackout dies, his back kibble is just gone -jolt has a different head in the movie -wheelies gone DOTM -when sam picks up brains, there is a shot where there he is not holding anything -during the mexican standoff- ironhode's guns disappear and reappear between shots -decepticon troops drop from the commandeered ship onto the battlefeild when Bee attacks soundwave -sentinal and megatron make the same "my face" growl from ROTF -when optimus is pinned by the fighters and shoots one, you can see the pilot fall out what are some you noticed?
In the first film, when the Autobots are arriving, Bee takes Sam and Mikela to this building and they get out and look up. Then he's taking them to the alleyway to meet Optimus. Why did he stop? Why not go right there? Also when Megatron is first released, he meets up with Starscream, who promptly transforms and does an unnecessery aerial manuever only to land a few feet away from where he started. What was the point of that?
i supose he was showing them (and us, the audience) the awesome sight of them arriving cos it was awesome
