I think for a summer comedy Sonic is okay. It won't change your life but this is also okay. It barely has to do with Sonic outside the furry critter looking like him.

Would I prefer if the movie was more related to the source material? Absolutely. But I learned enough about Hollywood to know how those movie tie-ins works.

Still, given what it is, a summer comedy for the kids and their 90s parents, the movie "works". Lower your expectations you may even enjoy it.

This also said, Sonic do floss during the movie so...
