I have watched two martial arts blu-rays over the last few days. Ip Man 2 & Ninja Assassin.
Ip man 2, not as good as the 1st one but still a good performance by Donnie Yen with the added bonus of Sammo Hung.
Ninja Assassin, probably one of the most entertaining martial arts films I have seen in a long time, plenty of limbs being hacked off by the blade of a ninja and a very good performance by a Korean pop star in the lead role. If I hadn't checked up on him I would have thought he was a genuine martial artist.
