Incredibly original idea for a movie what do you think?

I'll just give the synopsis. I'll try to make it brief. So it's about this nerdy guy who is madly love with the head cheerleader at his high school set in the year 2511. He knows he has no shot with a girl like her but he feels like he at least has to go for it. So he finally musters up the courage to ask her out and she says I WOULDN'T DATE YOU IF YOU WERE THE LAST GUY ON EARTH!! He is humiliated, so much so that he drops out of school and runs away hides from the world. He settles himself in the heart of the amazon rain forest where after several years he goes insane and begins experimenting with gene splicing so that he can create the first giant spider-octopus hybrid that spews gamma radiation from it's tentacles. He trains these creatures to wipe out every guy on earth besides himself of course. He successfully does so after an intense battle and finds his true love, but it turns out shes a . So wacks the ***** he just ***** a bunch of sluts and repopulates the Earth, but then an asteroid comes out of nowhere and the Earth is completely destroyed. But it turns out it was all an hallucination from a coma cause it turns out the girl had a boyfriend and he beat the **** out of him after he asked out the girl. So he goes back to school and lives for another 17 years as a tax attorney in a life of solitude and dies when he falls down a chimney into a heating boiler. He mistook a chimney for a balcony.
