"Twinkle Twinkle" is a bit like cold pizza - not that appetising but there are a few bits on there that are so tasty, you just have to sample them! I'll explain: In effect, this is a comedy with martial arts, not a martial arts film with comedy and unfortunatley much of the comedy is over-long and dare I say, childish. Being translated and dubbed into another language probably hasn't helped. Comedy requires a great deal of skill to pull off and it must be difficult to do dub-overs and keep the same timing etc.
On the other hand, the various fight action that occurs is truly top notch and a masterclass blueprint on how it should be done! The warehouse scene with JC, Yuen Biao and Andy Lau does more for martial arts action cinema than any Hollywood film in the last 20 years (check out YB's tornado kick/back kick combo after flipping off a crate!) The final showdown is a martial feast that makes you forget you're watching a "comedy", and even the little post motorbike chase scuffle between JC and Richard Norton is beautifully edited and features a background Rock Guitar style bit of music - giving it great atmosphere. Oh, apart from the shot where JC leaps out of the moving car and turns into the "Mitchelin Man" (blink and you'll miss it).
For the action, this is definatley worth owning but I'll bet most of you never watch the film in it's entirety more than once. I'd rather quite happily spend an hour and a half replaying the warehouse scene!
