Review: As it is often the case, the impressive and explosive trailers of Asian films add up to nothing more than lackluster stories. Similar to Unleashed (which was great,) Dog Bite Dog tells a story where men are raised as ferocious savage dogs that carry out their master's bidding. The main characters, an emotionally undeveloped, amoral killer who is matched against an equally unstable police officer, are far from the common heroes and villains we often see. In fact, by the end, you lose track of who you're supposed to empathize with, failing to feel even the slightest emotion for either of the men  whether that was the failure of the director or perhaps the underlining message he was trying to tell is up to you to decide.Although the beginning of the film was filled with intrigue and unpredictability, by the half-way point it slopped down to a humdrum story of survival and revenge. The suspense which was evident at first soon disappeared because of a grossly mismatched music score which brought down the potentially effective story telling. And in the end, you were left feeling that all that detailed background information and introspection of the main characters was somehow very unnecessary.On the plus side, the transition in story from point a to point b was quite atypical compared to US movies  so those who aren't familiar with Asian films and are tired of Hollywood's predictability should check it out.The white balance seemed off throughout most of the film. It was like looking into a picture shot on fluorescent when it was supposed to be set on tungsten. Maybe I'm the only one, but it strained my eyes.The movie also enjoyed playing tricks on you  an interesting build-up gave me hope for the slow moving story until it was diverted to a low budget, low speed chase scene. And just when you think you were going to get an unanswered indie ending with a mix of Shakespearean tragedy, you realize that it's not an ending at all, but rather a transition into a wacky country-music montage about peace and serenity.Throw in some grisly from-behind choke scenes, a moment of redemption unexpectedly brought back into savagery and back again the other way, Asians' fascination with bodily fluids and a horrible music score that didn't match the film, and you get the average bland Asian thriller.I just don't get why every fight scene was overlaid with clips of roaring lions I thought they were supposed to symbolize dogs? Ultimately, in the end, we are reminded about a true killer that still lurks amongst us  tetanus.4/10 Question: is it a negative review?

Review: What a shame that Alan Clarke has to be associated with this tripe. That doesn't rule it out however; get a group of lads and some Stellas together and have a whale of a time running this one again and again and rolling around on the floor in tears of laughter. Great wasted night stuff. Al Hunter homes in on a well publicised theme of the late 80s- that hooligans were well organised and not really interested in the football itself- often with respectable jobs (estate agent???). But how Clarke can convince us that any of the two-bit actors straying from other TV productions of low quality (Grange Hill) or soon to go on to poor quality drama (Eastenders) can for a nanosecond make us believe that they are tough football thugs is laughable. Are we really to believe that the ICF (on whom of course the drama is based) would EVER go to another town to fight with just SIX blokes?The ICF would crowd out tube stations and the like with HUNDREDS. Andy Nicholls' Scally needs to be read before even contemplating a story of this nature. The acting is appalling and provides most of the laughs- Oldman is so camp it is unbelievable. Most of them look as though they should be in a bubble of bath of Mr Matey. A true inspiration to anyone with a digital video camera who thinks they can make a flick- go for it.

Review: When I was younger, I thought the first film was really good in childhood, so I decided to see the sequel. This is an example of why some films shouldn't have sequels, because the first film is usually best, and it is. Basically now that Ariel and Eric are married they have a daughter who isn't allowed outside the house because they are worried about the sister of Ursula (the octopus legged villain from film one), Morgana getting to her. When the kid gets out she asks Ursula's sister to turn her into a mermaid, like her Mum was. This makes Ariel go back to the sea to find her. The same good voice artists, it's just the story that could have had a bit more thought. Adequate! Question: is it a positive review?
