If you're watching "True Detective," it's hard to buy that Vince Vaughn's performance as crooked Vinci ringleader Frank Semyon could put the defibrillators on his career. The actor, long known for his goofy comic turns, postures a faux-seriousness that whiffs of Matthew McConaughey's brooding season one turn, and a face that says, "I'm thinking about Emmys." (When "Delivery Man" opened in 2013, we called him a "toxic comedian" who "has burned many smart moviegoers over the years.") But Vaughn clearly wants to buff his dramatic chops.
