I thought he was a pretty good character, who got the short end of the stick. He seemed menacing at first, and Tony Todd's voice acting really brought him to life. The scene with him, Megatron and Starscream on the Nemesis was my favorite scene of the movie, simply because we FINALLY got to see the villains get some characterization. His announcement to the world was creepy, and I was surprised to see him actually being one of the Decepticons attacking the aircraft carrier. Unfortunately, this was right before the second half of the film, and immediately after that scene everything else takes the back seat to the hour long wild goose chase. And then we got to the ending battle, which was so cramped he had barely any time to do anything. Even so, I thought his duel with Prime was great, very savage and intense. It felt like if Prime didn't have Jetfire's parts, Fallen might have won. And his death was certainly memorable, I'd call it a triple fatality.
