There are thousands of people that didn't even get a chance to see Kasparov compete and they are excited to see him play now. The excitement isn't really because he doesn't play "boring chess" but rather because he is considered by many one of the greatest ever, which has nothing to do with his style of play.
And to the game you mentioned about Lasker. I agree, he played the ending almost flawless and held on to the draw, Dvoretsky analyzed his game and said that the only inaccuracy he did was at move 75, and if there's anyone's analysis I trust in endgames it's Dvoretsky's... But you're forgetting one thing, that same Lasker that played the ending almost flawless was the same Lasker that was down an exchange and had to fight for the draw.
GM Garry Kasparov is ourplaying these overrated so call super GMs, I believe if it was standard time control Garry will be crushing all these duffers. There nothing expressive with Carlsen play or the top ten players; Kasparov bring a element of excitement and daring in his games, something lacking Carlsen and the top ten elite GMs.
Man, you really are showing a lack of understanding of what has been happening in St. Louis in the rapids.
