Sucks? Boring? circus shows? That's a load of crap. You could say that about any virtuoso guitarist. Anyone that's so unbelievable to watch could be labeled as a gimmick type because they're using what they're capable of doing to make us look at them. His music's good (this is my opinion) but his capability of playing the guitar is excellent (this is moreso factual). You could say Steve Vai, Yngwie, or Satriani are just pulling flashy stunts when they tap or shred because they do it in the way that they do it. Circus tricks don't exist on the guitar, only capable and incapable.
