I loved a lot of his earlier stuff - fantastic guitar technique. I lost interest later as the songs weren't as good (to me, anyway) and live he just seemed to solo through everything. He always had the reputation as having an enormous ego, but I watched his interview with Rick Beato and really enjoyed it. I think it was Steve Vai who said something along the lines of 'say what you like, but Yngwie raised the bar for all of us'
