I was not a fan of the first Sonic movie, I thought it was absurdly generic and didn't get a laugh out of me once. But I got more out of the sequel, I don't know if I thought it was downright good, but it was very watchable and mostly pretty fun. In comparison to Mario I would put it along with the first, and that's based on what I remember since I haven't seen Sonic 1 since release and I can't claim it was particularly memorable for me. Though visually I like Mario way more, and while I don't like the Brooklyn backstory they go for, I prefer that over taking Sonic out of his own world and putting him in our reality.
