Here's the deal. Even though I too, don't think much of him as an actor (in fact, I'm still fuming at how badly the Max Payne  movie turned out to be), that doesn't mean I think he has no place in the industry. After all, not every actor out there needs to be Robert De Niro. I thought Wahlberg was fantastic in The Other Guys , playing a straight man opposite Will Ferrell, which was also part of the reason why much of the humour worked.
So you know, Mark Wahlberg is the kind of actor in the same vein as Arnold Schwarzenegger and Sylvester Stallone, the only difference being it's no longer the '80s, Golden Era of action movies is over, and we have the internet now. But chill out, Wahlberg. Even if people don't regard you as a real actor, you're still entertaining to watch.
