I personally don't mind "asshole" characters so much. When it gets bad is when we're expected to automatically forgive anything he does because he's ShinkenRed and he's the all-powerful Red Ranger hero, or he's GaoSilver and he's the angsty pretty boy, etc. etc. (the show's pet character, in other words)
That does sound like the kind of thing that Next was complaining about though -- personality flaws that are not acknowledged by the show as being personality flaws.
I mean, I think most people watching Kabuto would say to themselves 'holy crap, that guy is an asshole.' Being an asshole is a pretty big personality flaw! But then the show says 'no, he's not an asshole. He's a perfect human being.' What you're seeing doesn't match what the show is telling you; that's when it's bad writing.
