I suppose technically MUNICH is his best movie from the 2000s, but I would still pick CATCH ME IF YOU CAN over that. Truely an unashamed, entertaining little Tom & Jerry-esque chase movie. Spielberg gets to play around the 1960s aesthetics from his youth (Leonardo DiCaprio in that movie theatre enraptured by GOLDFINGER, that was surely young Beard.)

(And unfortunately the movie based off a "true story" couldn't fit in the crazier shit the real-life Frank Abagnale pulled off. My favorite was while in jail in Georgia, the guards for whatever reason suspected he was a FBI mole and unbelievably asked him upfront. He said yes, and that day he got to walk out of jail.)
