Zendaya may could get replaced but at the same time, I don't think so either. I'm thinking if Sadie do play MJ she doing it temporarily and like many said, Sadie could dye her hair or put on a wig for another character. But she did denied Jean Grey when she was shocked at the news on X.

The kiss wasn't needed in the finale, only Riley and Gabriel. I rather Matt and Eve be bantering friends then to date. Their personalities would cause a regular couple in reality to get divorce. So it was a wrong approach. Matt should date another woman.

Of Course Amy going to play a big role in Sonic 4. It sounded like your headline was criticizing the movie. Whatever the Sonic writers do, it will always be awesome. Just like introduction of Shadow

I rather animated hedgehogs then human characters. Because hey it's Sonic for goodness sake and Ben Schwartz love it the same way. The franchise is expanding and Sonic franchise didn't have a lot of human roles the same way. If you think that's suppose to be a critical thing about the film, you doesn't know what you talking about.
