Eh probably should of said my opinions on this subject here instead of the Sonic thread. Didn't like the dance scene, Altered Beast maybe and Sonic the Series & Knuckles.
I found the Siberian tavern scene to be my second least favourite scene in the movie. I found it rather "Well this movie is for kids, lets give them an obligatory dance scene with pop music.) I also found the whole thing rather cartoony with the granny knitting a pirate flag and the fish head saying "run". Isn't the whole point of Sonic and Tails being on Earth is a sense of realism?
When I first saw the pavonka guy, I thought he was going to turn into a werebear as a reference to Altered Beast.
That would of been so much cooler than a dance battle and would leave audience with a lot of questions that could be answered in an Altered Beast spin-off.
This scene and the wedding scene are definitely not for Sonic fans but more for general audiences.
Most of kids laughed like crazy on this scene in the cinema where I went and most adult laughed a lot at the wedding scene.
While it was cooler for SEGA fans if it was related to Altered Beast or other SEGA games, the movie's also trying to appeal general audiences too.
Who knows if any of them would be new Sonic fans later.
At least one of my kid's friend becoming a Sonic fan too after the movie and his favorite part was the dancing scene.
His favorite game is now Sonic Adventure 2 Battle, after playing two players mode with my kid.
