You can't expect much from a seriously low budget movie with a seriously naff concept. I bought this on DVD in an end-of-line shop on 50% discount, so I think I got a good deal for my 0,75.
Okay. The plot. Barely a plot, there's a bunch of badly rendered satellites that take energy from a solar flare and convert it to a sort of blue magnetic pulse that is blasted down to a ground station where it is picked up by an array of things that look like a cross between a television aerial and the framework thing that holds my tent up. If you're busy gagging right now, please disable the scientific part of your mind for this movie runs on "looks good on screen" rather than any sort of coherent logic. During the first run, something goes wrong, lights flash, nerdy people look worried. Some sort of twirling blue magnetic field wanders off from the array, then everything calms down. Yes, I said a blue magnetic field, for this is obviously a parallel universe where magnetic fields are visible. That'd be kinda cool, imagine science class. Anyway, this magnetic field turns out to be a tornado (yes, really!) sucking up metal things as it goes. I don't really see I needed to mention this review was spoilers because, you know, clue in the title. But with IMDb's scary-looking blacklist message, I'm not taking risks. There's the scientist, the greedy company big-cheese who wants to cover it all up, the hapless civilians, the "will we save the town/the capital/the world/etc" question. I think you pretty much know how this will go, these sorts of movies rarely and with "...and humanity was extinct" because that would be a downer.
So, since this review contains spoilers, I will point out some of my favourite parts. Firstly the girl was pretty cute which is always a good thing, but the rebellious boy? Didn't buy it. Special kudos to the girl for not only being able to help lift a massive lump of concrete, but to do so wearing high heels. Then there's the hard-ass biker chick who is about as hard-ass as the boy (in other words, not). I almost choked on my tea when they had a shot of the tornado with all its metal crap flying around and there was the chainsaw, still running. What? Actually it was pretty funny. Like the tornado sucking up metal objects like cars and mobile homes, but curiously leaving wooden structures intact because we know well that wooden houses don't contain nails or wiring or water pipes. I guess the budget didn't extend to that sort of thing. Then one destroys huge swathes of Paris, but nobody seems overly concerned because, hey, we saved Phili. Not to mention that there's no significant ore deposit leading to Paris. According to the so-called science, the tornado should have ravaged the Lorraine region with its significant ore deposits.
However, having said all of this, I can say that the "Metal Tornado", on the whole, was an enjoyable hour and a half. I'm just not sure they intended for it to be a comedy!
