Make war, not love. Why do we mock actors who romance while lionizing those who do violence?

It's worth noting the deluge of praise that has greeted Matthew McConaughy over the last 18 months as he's basically cast off the high-profile romantic comedies of the last decade in favor of theoretically more serious work.  When Matthew McConaughy appeared in mainstream romantic comedies, he was a sell-out movie star, not a real actor.  Regardless of whether he was actually effective in said films (Yes - How to Lose A Guy In Ten Days and Ghosts of Girlfriends Past; No - The Wedding Planner, Failure To Launch, and  Fool's Gold), the idea that McConaughy was headlining relatively popular and often profitable entertainments was considered a net loss because he was using his talents in a disreputable genre.  But now that he's appearing in legal thrillers (The Lincoln Lawyer), male-centric dramas (Magic Mike), and ultra-violent crime pictures (Killer Joe), *now* he's being proclaimed as a real actor worthy of discussion. In short, McConaughy made films that were embraced by mostly female audiences and was derided for it.  Yet when he moved into male-centric genres, he's suddenly a respectable actor turning over a new leaf.
