Last I heard it had gotten some mixed-to-poor reviews from critics, but actual audiences who got to see it early liked it a lot - at least that was the impression I got from a Google search (yes, I put '-ai' on the end*, so it wasn't just Gemini making shit up). I've seen a few movies like that, though most of them fell into the 'not strictly speaking good, but very entertaining' category; since I haven't actually read any other reviews, I was going to see it anyway, but now I might actually commit to getting tickets.
Still gotta watch Sonic 3 as well, I liked the first two a lot.
* It really works. Try it (without the quotation marks).
