This lacklustre disaster flick should have been so good: it features tremendously good special effects scenes of 100-metre high waves tearing through a city, laying waste to anything and everything in their path. These scenes alone are among some of the best bits I've ever watched in the whole disaster genre; destruction and mayhem on a massive scale, with carefully-crafted CGI bringing the chaos to full and authentic life.

It's a shame, then, that the surrounding movie is so poor. Tidal Wave takes an hour to get to the disaster stuff, and until that time we're treated to…Korean comedy. Now, I don't mind a bit of comedy, the quirkier the better; THE HOST had a lot of fun moments. But this comedy is something else, the comedy of ridiculous characters behaving ridiculously, almost on a sub-slapstick standard. The over-the-top acting is absolutely appalling; I avoid American comedies on principle but this is even worse than those.

Of course, disaster movies always have to build up to the disaster, and I fully understand the need to develop the characters before dropping them in the clag. But, in my mind, the film should always be about the disaster, even before it occurs: have characters making warnings that are unheeded, or build suspense and foreboding with minor events preceding it. DANTE'S PEAK is a case in point of how to achieve this. TIDAL WAVE sits in a completely different, and entirely superfluous, genre until the actual disaster occurs.

Once the chaos gets underway, things get a lot better, although there's a reliance on overwrought melodrama which will test the patience of even the most hardened viewer, I imagine. Endless scenes of characters facing death, drawn out in painful slow-motion and with maximum crying, screaming, sobbing and telling each other they love them. Such scenes are a personal pet hate of mine, and they threaten to overwhelm the film even when the going gets good. It's a real shame, as with access to those special effects TIDAL WAVE could have, and should have, been a true great.

A massive tsunami wave caused by an undersea earthquake hits the vacation spot of Haeundae on the south coast of Korea.

While writer/director JY Youn deserves praise for taking time to develop the mostly engaging and interesting characters, the first hour or so of this film proves to be kind of a slog to endure thanks to way too much goofy humor and a teeming surplus of sappy soap opera-style melodramatics. Fortunately, things get extremely intense and exciting after the big one hits: The special effects are pretty spectacular, the mondo destructo sequences are breathtaking in their grand scope and severity, and the various heroic sacrifices and last minute reconciliations possess a certain endearingly cornball charm. Among the stand-outs in the large cast are Ji-won Ha as the feisty Gang Yeon-heui, Kyung-gu Sol as regretful fisherman Man-shik, Min-ki Lee as likable lifeguard Hyeong-shik, Ye-won Kang as the stuck-up Hee-mee, and In-kwon Kim as the bumbling Dong-chun. A bit drawn out, but overall a solid and enjoyable disaster epic.

Disaster movies have been fine-tuned by Hollywood into a fairly reliable and polished formula. One of the ingredient is usually a good dose of melodrama. Now, Asian cinema as well, is known to spice movies with melodramatic bits.

It therefore doesn't take a rocket scientist to figure out what an Asian take on disaster movies is gonna end up looking like: A melodramatic extravaganza.

The first hour of Haeundae (also known as Tidal Wave in English) consists of setting up the table by presenting the cookie-cutter characters (played by a rather weak cast which tends to overact) and their clichés relationships. The script and story is pretty standard for the genre (you've seen all of this in Twister, Armageddon, many of Emmerich's movies and so on) but the writing is just... immature. As if the script came straight from a high school play. I must still praise some of the comedy bits, which are indeed funny and make certain characters more likable. Unfortunately, the dramatic bits are as (unintentionally) funny as the comedic ones and that is a problem.

The final part of the film is where the disaster unleashes and ends up being a poor payoff. The special effects, cinematography, editing are uninspired. This film suffers from poor direction and you immediately feel like you'd rather catch an old disaster flick on cable TV. But what absolutely kills the disaster scenes are the tear-jerking attempts. It's like the director is trying to squeeze a dehydrated fruit and fill a glass with orange juice.

It still deserves a 3 because there is some heart to it and it maintains your interest with some of the quirky characters. Plus a few comedic bits are also worth it. But if you're not a fan of the genre, expect a big waste of time.
