Like most of you OT fans who say TPM, I knew that Darth Sidious and Chancellor Palpatine were one in the same the second he appeared on the screen and we heard the eerie "Emperor's Theme." I didn't really feel any surprise or disappointment by it. After all, if we've seen the OT before the NT, then we know that little Anakin Skywalker grows up to become Darth Vader.

It was just like when you make a movie about Palm Harbor, Titanic or September 11, 2001 (BTW, I mean no disrespect to anyone). If you've researched the history before you see the movie, then you pretty much know what to expect.
