As it happens, the weakest part of Ip Man 3 is its run-of-the-mill, almost juvenile potboiler plot.

Stone-faced martial-arts star Donnie Yen does a lot with a little in wuxia weepy Ip Man 3, the rare kung fu film whose sentimental dialogue scenes are just as good as its stripped-down action sequences.

Ip Man 3, set in Hong Kong circa 1959, combines the customary, inventively choreographed action with an unexpected emotional depth, proving as hard to resist as its entertaining predecessors.

Ip Man 3 credibly conjures the period with soundstage sets, rock-and-roll oldies and slicked-back hair. But director Winston Yip shows less concern for authenticity in Ip’s antagonists.

This time, celebrated action director Yuen Wo-ping, taking over from Sammo Hung, ensures the film’s fight sequences remain the film’s primary focus, although the overall tone is smaller and quieter, reflecting both the personal drama Ip Man encounters and Donnie Yen’s own encroaching retirement from kung-fu cinema.
