I love me some martial arts movies. Love 'em. Even when they suck I love 'em. Plot, acting, direction. Nothing really matter in these movies except for how much ass someone can kick and how fast they can do it and Ip Man has it. It has it all, in fact. One of the few martial arts flicks that has great everything.
Ip Man is about the story behind the famous teacher of Bruce Lee, Ip Man (last name first, first name last) and his battle against the Japanese in the Sino-Japanese war in 1937 (and for eight years after, in case any history buffs try to correct me). Basic plot has the Japanese Army wanting Ip Man to teach there men, while he is all about the honor of the Chinese and refuses. Donnie Yen is a great martial artist and deserves much more recognition here in the states then what he has. Dude studied Wing Chun (Man's fighting form) for nine months before hand and that's fast for this stuff. Amazing fights and great acting and story. If you are a fan of these movies, it's a must. If you're not, just watch it for the fighting.
(And like most martial arts films now, there is wire work. Sorry if that bothers you)
