I know all you Twins fans out there have been just gnashing your teeth waiting for their next movie. After all, it's been nearly two years since their last teaming with 2005's House of Fury. Well, you can all relax now that Twins Mission has been unleashed. And if you're not a Twins fan? Well, you still might get a kick out of this dopey-but-enjoyable action picture.

The movie's slim thread of a plot has Ah Gil and Ah Sa as a pair of circus performers who are actually kung fu masters (well, aren't they all?). Their old master (Yuen Wah) comes to retrieve them, as well as several other pairs of twins, so that they can help a pair of monks (Sammo Hung and Wu Jing) who have lost a relic that can magically cure any sickness.

Oh yeah, the big hook of the movie is that the relic is also being pursued by a group of evil twins. Not exactly Shakespeare or even Wong Jing on a good day, I know. But then most people out there aren't checking out this movie for the plot, and ostenibly Twins Mission delivers on what it promises -- big and loud action.

That being said, Twins Mission certainly has its' share of problems. For starters, it's getting pretty ridiculous to pair Choi and Chung as actual twins in films, since with each passing year, they are looking less and less like each other. They're still cute and work well together, but really, it's time to retire the gimmick.

Also, for what is supposed to be a "prestige" production, Twins Mission just doesn't feel very polished. The movie was shot on both film and digital video, which makes it look incredibly cheap in parts. The soundtrack feels more like a stock score that was simply spliced in instead of being created specifically for this film.

Most damningly, Twins Mission features absolutely the worst CGI seen in a movie -- even cheap straight-to-DVD stuff -- in years. Specifically, there's a sequence towards the end where the Twins fight a bunch of snakes that look like cutting-room rejects from Anaconda 2. Shoddy work like this sometimes makes me wonder if Hong Kong film-makers are actually taking their work seriously.

Speaking of the end... well, there really isn't one. Since a sequel has already been filmed, the producers decided to pull a Kill Bill and slap on a cliffhanger ending. This sort of thing just smacks of greed and lazy film-making, and is most definitely not the direction the Hong Kong movie industry needs to be going in. Big films like this should leave the viewer wanting more, but the film-makers shouldn't be so blatantly obvious about trying to get asses in the seats for a sequel.

Despite all of this, I actually still enjoyed Twins Mission. And before you ask, no I wasn't drinking, taking cough medicine, or suffering from a brain injury. Sometimes you just need a mindless action movie, and Twins Mission fits that to a tee.

Yes, it can't come close to the classics of yesteryear. Yes, it's often cheesy as hell. Yes, it won't earn you any cool fanboy points on internet boards for liking it. But just sit back and relax, and you should have a fairly good time with Twins Mission.

RATING: 6
