see, I'm cool with a movie like this - but it has to retain some realism. If a SINGLE monster like this appeared ,our badass military would put 3 missiles in its head inside of 7 minutes, and it'd be over.
now, if there was a movie where somehow, the monsters were controlled by something like an alien, and specifically targeted military/govt stuff, and maybe there were thousands of them planted that grew all at once one day, that'd be badass.
But the idea of 1 to 3 of these big old things wrecking the country, sorry, just TOO unrealistic in a world where my premise somehow makes perfect sense.
