Which of these films is worth watching? `Wanted', `Inception', `Shutter island'?

I first saw Shutter Island, back in February of last year. Martin Scorcese did a fantastic job with it. It truly was a wonderful suspense/thriller--with a touch of film noir. But Christopher Nolan's Inception is a masterpiece. I was thinking to myself in the theatres as I was watching it "who could ever top this!?" So yes, definitely, Inception is the movie to watch, Shutter Island also a must see. Wanted..eh, I wouldn't p up the opportunity to watch it, but I really don't have much of an interest to see it. From what I hear it was just "ok".
