Continuity mistake: In the party scene when Sam is standing and holding his drink, every time it switches angles the amount of liquid in the glass keeps changing. First it's full. Next it's half empty. Next it's almost full again.
Continuity mistake: When the Jordanian helicopters are on approach, there are painted with a desert camo. The one that is shot down first and lands next to the soldiers is all of a sudden black.
Continuity mistake: When Jetfire says ''A living Prime! I don't believe it!'', he is leaning on a blue wall. When The fallen arrives moments later to steal the Matrix, Jetfire is nowhere near the wall, while at the rate he is crawling, it would take some considerable time to cover any distance.
Audio problem: We get a shot of a Predator drone taking off, and it is driven by a propeller. However, it makes the sound of a plane with a jet engine.
Revealing mistake: The same shot which shows the sun is used several times in this movie - please note the cloud next to it. Two of these shots have Jetfire in it, and three are after that.
Continuity mistake: When Alice and Sam are driving away from the party in Bumblebee after she gets squirted with "fluid", we see that they are driving down a city block. Each subsequent shot out the side windows from inside the car show distant blurry lights - not buildings we should be seeing.
Answer: Well, for one thing, he blew up Sam's room and half their house. Sam knows Bumblebee meant well, but is still mad at him because of the destruction he caused. It's the equivalant of a child knocking over a vase while trying to hit a fly.
