If there's one thing that's easy to forecast, it's that weather movies rarely fulfil their makers' expectations. Neither Twister nor A Perfect Storm lived up to the hype about their special effects, so what chance can a low-budget thriller such as this have of success? Martin Sheen gives his all as the leader of a government research programme that develops a weather controlling device, but Luke Perry is woefully miscast as the computer whizz who takes to the skies when the device threatens to destroy Los Angeles. This far-fetched premise is timidly handled by director Harris Done.
