Hellmuth didn't get nicknamed "The Poker Brat" for his "antics", he earned it because he whines like a ***** every time variance occurs and has the general attitude of a Hollywood Hills 7 year old.
He lacks any class, even when playing against amateurs such as Fishman. Sorry Phil, not everyone is a pro. I would much prefer to watch the "antics" of a Phil Laak, Humberto Brenes, or even Tony G, because they are likable and aren't malicious with their goading. (Except for maybe that rant by Tony G about Russians)
I think as a entrepreneur and competitor, he is good for the sport. But as an example on how to conduct yourself in defeat/victory, and displaying humility he is not. All the kids coming up see Phil act like a moron at the table and think its OK, but its not. People died for doing much less back in the day. Respect the game. The stuff that goes on today at a poker table by comparison would never fly in other traditional class sports such as golf.
