The Disaster:
When a large stormfront threatens to let loose a number of tornadoes in an area commonly known as the "Tornado Belt," it's up to a plucky Storm Chaser (Hellen Hunt) and a guy with the regrettable nickname "The Extreme" (Bill Paxton) to put a bunch of little plastic balls into one of the tornadoes for science.
Why They Should Calm The Hell Down:
We're certainly not going to argue that tornadoes aren't a destructive force of nature. That would be retarded. However, it's important to keep in mind that the average tornado-related event doesn't actually last very long, certainly not long enough to base an entire movie around.
The solution, obviously, was to make a movie about people who are dumb enough to run right up to one tornado after another and try to stick their balls in it.
But, even if you're willing to buy into the idea that the heroes' mission is worth all this ridiculous weather chasing, and some people obviously do, you're still left with the fact that these particular tornadoes are pretty much wimps. Sure, they're ready to tear a house apart or throw around the occasional cow, but time and time again the heroes drive right up to the funnel clouds, as if you actually have to jam your head inside one for it to hurt you.
For the big finale, our protagonists actually pass through into the eye of an F-5 tornado (read: a seriously fucking dangerous tornado) and emerge completely unharmed because they hung on really tight.
"This was such a stupid idea."
Yes, unharmed by the tornado that's full of debris flying around at speeds that can drive a piece of straw through a tree trunk.
How They Solve the "Problem":
Keep in mind that the situation that needs solving isn't the actual tornadoes themselves but rather the problem of getting a bunch of little plastic balls into one of these tornadoes. So, it makes sense that the day would be saved by Pepsi Cola.
