It goes on 8 minutes too long, spax looks like a guy from "To Catch a Predator", he cuts Ken off numerous times, is disorganized, has a tinge of anger in his questions and looks to be a douche. That's what made the interview terrible for me.
Also, a good interviewer should be friendly. You can still ask the tough questions without an attitude. This dude definitely won't get this opportunity with future Sonic games. He's probably on the SEGA shit list with TSSZ.
