Dennis Quaid, he’s a puzzler. He has a natural charisma that transfers so easily to the movie screen, it’s like he isn’t even trying. But then there’s the films where it’s truly like he isn’t even trying. Take “The Big Easy” (1986), a New Orleans whodunit exacerbated by Ellen Barkin’s weak portrayal of a district attorney. Quaid’s uneven Cajun accent comes off like a horrible impersonation of a deaf person. Of course, he’s playing a guy that acts like he doesn’t give a shit, so he almost pulls it off, but you always wonder whether Quaid himself actually gives a shit.
