Yeah. It's why the Avengers movies worked. The audience already knew the stories of Thor, Captain America, Iron Man, Hulk, and to a lesser extent Black Widow and Hawkeye from earlier movies. Spider-Man 3 probably couldn't have worked just fine with the introduction of both Sandman and Venom. But, for reasons I don't understand, the writers decided to go back and change the events of the 1st movie by making Cain Marko the real murderer of Uncle Ben. Come on, the audience saw the first movie. You can't just tell us what we saw wasn't what happened.
