Am I the only one who doesn't like the Figure-8/Infinity running blur from Sonic CD being used? I mean, It was okay in Sonic CD as something to differentiate the game a little, but it was never really used elsewhere, and it just looks odd. Like I can see a circle blur being created from running very fast, but a sideways 8? How does that even work?!
Well anyway, I agree I loved the Sonic OVA and CD intro/ending look the best.
