The more I think about the ending, the sight of Optimus flying off into space like Superman, the stupider it becomes. Why didn't he take the Knight Ship? Was he disgusted by it because it had been "disgraced" by Lockdown? Is there a space ship on a nearby planet or moon that he's flying to? Is he flying to the Nemesis? A better ending would be one in which Optimus subdues Lockdown and imprisons him on the Knight Ship and then commandeers it to find the Creators. Another better ending is one in which Optimus transforms into a spacecraft or reverts to his space-flight-capable protoform. Anything but the ending that's actually in the movie would be better. WTF, Michael Bay? C'mon, bro.
