These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: IP Man
Anvilicious: Foreigners: Bad. Chinese Martial Arts: Good.
Complete Monster: Twister the British boxing champion from the sequel. Prone to racism, open disrespect for Chinese Warrior Culture and homicidal bloodlust in his fights.
Fridge Logic: Master Hong, I know it's noble not to give up, but you're not going to win... and I don't think your wife and seven children care about honor as much as you do.
Genius Bonus: For anyone with an upbringing in a Chinese household, a feather duster very similar to the one Ip Man used in his battle with the Northerner is a source of dread for much the same reason as how it's used in the film.
Please, you don't need to be raised in a Chinese household to fear that thing. Multi-purposed or not, a switch is a switch.
Memetic Mutation (Going up against the Iron Man movies at the box office has led to photoshop mashups of both movies' posters, dubbed with the convenient Portmanteau Name "Ipron Man".)
Moral Event Horizon: Colonel Sato makes it clear very early in his appearance that he is a Smug Snake, but crosses the horizon after he coldly guns down Master Liu for losing an extra round he volunteered for. It is made especially stark because up to then the combat had all been hand-to-hand martial arts fare.
Twister beats Master Hung to death in what is meant to be a exhibition match. Bad as that is, it's not this trope. This trope comes into play in the press conference afterwards. Rather than showing ANY remorse at the press conference held for his innocence, he gleefully mouths off about how he is going to murder every Chinese Warrior in Hong Kong during the next match held to clear his name.
Sequelitis: The horribly-rushed (and horrible) "prequel" Ip Man The Legend Reborn is so terrible (tacky soap opera romance, gross mis-representation of Wing-Chun) that it has been declared as CanonDiscontinuity by the fans of the first two films in general and Wing-Chun practitioners alike. Averted by the sequel, which is very well received.
Well, it really isn't part of the Ip Man movies by Wilson Yip. The Legend is Born was directed by Herman Yau, but they reused a lot of the same actors.
