First of all, don't get fooled by the title or the description of the press release. There is no storm in this movie. I was expecting action sequences in the key of Korean movies like the drama-thriller ''Tidal Wave'' which takes place during a mega tsunami or the spy thriller ''Typhoon'' but ''Firestorm'' turns out to be a more conventional thriller. This movie may not be very unique but it's a quite entertaining two hours for fans of the action-thriller genre.
The story where a veteran police officer and his assistants face a notorious thief and his cruel gang is nothing new either but the movie includes a couple of side stories. Some people may say that these side stories are only hiding the weak main plot and rather distracting but I thought they were what made this movie a little bit better than just average. The relationship between a naive criminal who wants to leave his past behind and start all over again with his proud but sad girlfriend is really touching. This side story adds some emotional depth to the movie. The story of an undercover agent and his autistic daughter is also quite intense as it turns from a passionate story to the grisliest element of the entire movie which I found hard to digest but absolutely intriguing. The acting from the secondary actors is very good while the main actors Andy Lau and Hu Jun are not as outstanding.
An important element of this movie is obviously the fast-paced action sequences. Some of them are well filmed and really breathtaking. One can really see that these scenes were filmed by experts and that there is a solid budget behind the movie. I'm not a fan of CGI effects but the special and visual effects are bearable to well done in this movie. On the other side, some of these sequences are overused, repetitive and feel artificially stretched towards the end of the movie. Some of them are simply over the top even though these scenes are at least never becoming ridiculous slapstick elements as it's the case in several contemporary Hollywood blockbusters like ''A Good Day To Die Hard'' or ''Fast & Furious 6''. One really gets the impression that the action sequences and side stories try to hide the ordinary main plot which fails to come around with true surprises.
If you are feeling for a fast-paced and professionally shot action- thriller, you can't go wrong with this movie. Anybody who's expecting something more like a great plot, outstanding acting or revolutionary effects should watch another movie.
