So Mark Wahlberg as a youngster was a bully. I don't think that's so important if his bullying didn't continue into adulthood. We all make mistakes, especially when peer groups approve. I doubt young Wahlberg was alone in his rock-throwing forays. He's from a poor section in Boston, riddled with gang and racial violence.
I give Wahlberg the benefit of the doubt. However, I cannot forgive him for his mediocre method acting. He's second rate, with a staunch following of good ole' teenage boys who cherish action flicks, lots of shootings and explosions and terrible bad guys who always are defeated by the wrapped-in-the-flag super hero. Hooooorawwwww.
Wahlberg, I suspect, is just as phony as the characters he badly portrays.
