I know there's a number of Season 3 fans out there, but I found it nigh on unwatchable. I and many, many others were hoping for Optimus to return, and so we got our wish. But more to my point, we got it in a very good two part episode with some extra effort in the animation and some pretty amazing touches in the writing - not the usual 30 minute toy commercial that lacked respect for the intellectual property behind it. I especially liked how Rodimus wasn't just chucked aside like scrap metal. He had a truly heroic instrumental role in bringing Optimus back, and it was his faith in Optimus and courageous efforts made it possible. It was a respectful goodbye to a leader that may never have had the respect of most fans, but whose character required a well thought out part in its own replacement. The hate plague as a plot device may not satisfy some people, but I thought it spoke to Optimus Prime's core values. In the end, only wisdom abolishes hate. It was a fitting way of bringing back the character. Even if it was all too little too late, it was a great two part episode with special meaning.
