Although this movie was very obviously made on a low budget, it does a decent job at depicting the weather events that are the main subject. Weather disaster films have a responsibility to make it clear to the audience which behaviors are safe and which are unsafe, and this movie sets a good example in many ways. However, in the same way movies that depict people running into burning buildings as heroes encourage extremely dangerous behavior in viewers, the way that the main character is shown as a selfless hero for putting himself in dangerous situations to help his family members may encourage viewers not to prioritize their own safety in similar situations.
The addition of a meteorologist as one of the main characters is a great help to the movie, because it means that the movie includes the perspective of someone who knows what they are talking about. At the beginning, that character makes observations about the sky and uses weather-related language to point out indicators of a potential tornado, like characteristics of a supercell storm, the anvil on the cumulonimbus cloud, etc. He is also there to be a voice of reason not only to the characters but to the audience, and educates throughout the film in response to people making bad decisions. He corrects someone who boasts of his intelligence in driving home to escape the tornado while the others were staying, saying that most people killed during tornadoes are in vehicles when it hits. He gives the correct advice to find a place underground such as a basement or storm cellar.
That said, there are several inaccuracies and dangerous behaviors that are not corrected. For one, the movie shows the characters taking time to open the windows when the wind gets really strong, which is a waste of time and won't make a difference if a tornado hits your home. They talk on corded telephones during the lightning storm, which is dangerous to promote as lightning can travel through telephone cords. Mainly, though, the characters also take way too long to enter the storm cellar, a reckless decision that is never explained and was presumably just there to add suspense. The main character only considers going downstairs when the siren is on, and then decides to stay in the main part of the house when it is switched off. It is much smarter to make decisions based off your surroundings than the on-and-off sound of the siren, since not going down earlier put them in a lot of unnecessary danger.
There are things that the movie did well in depicting tornadoes, and things that promote dangerous and unsafe behavior for the sake of making a more dramatic story. Overall, the movie is entertaining, but viewers should be careful and make sure to educate themselves on what to do if they find themselves in the scenario that the characters did, because many examples in this movie should never be followed.
