Fantastic film. The writers really did their homework on the franchise. I had to restrain myself from yelling when they pulled stunts like Sonic doing the Adventure pose, the snowboarding section being a giant Ice Cap Zone reference, Super Sonic showing up at the end...
Honestly, I haven't had this much enjoyment out of a movie in years. Even the acting was on point, though the dialogue was very cheesy, and the story a bit tropey. But it's also a film targeted at children, so I'm not gonna knock it on that. If anything, the digestibility is appreciated, as I didn't watch the original film and thus lacked the context it provided.
Honestly, only thing that could make a sequel better is pulling some more music from the games. Would love to hear a few tracks from the Adventure era.
