While guarding the Master Emerald, Knuckles encounters an unknown enemy, but before he realizes it, this new foe steals the Master Emerald, causing Angel Island to fall from sky. This new creature’s name is Nazo, a sentient being created from the negative energy of the Chaos Emeralds. His plan is to steal the Emeralds to become more powerful, and so it's time for Sonic and his friends to stop him before it's too late.

An action-packed slog
I think this is a new genre that they're all sort of working their way through it and haven't got all the kinks worked out yet but it's a genre that works for me.
The storyline feels a little thin and moth-eaten in parts but this sequel is plenty of fun.
Great movie. Not sure what people expected but I found it highly entertaining.
