The thing I find hilarious, is that Micaela could fly to Sam's school in a matter of minutes, and Sam and Bumblebee could drive to Petra in minutes..... yet it took seemingly FOREVER for Sam and Micaela to make their way to Prime with the magic Matrix dust at the end! lol
Just one more example of how incredibly sloppy and haphazard the plotting in this movie was. I don't mind mindless action, but there at least has to be SOME kind of internal logic underneath it all. Once a movie starts jumping around randomly for no reason, that's when I start tuning out.
