"Limitless" - The writers fail at middle school math, which ruined the whole movie for me

The protagonist uses the genius pill to start day trading to make money. He says he took his last $800 and started trading. The first day he makes around 2k, the day after that around 7k. So he's basically tripling his money every day. Then he says "it's not fast enough, i need more money". So he goes and takes a loan from a russian gangster, and fails to pay it back which is basically what the entire second half of the movie revolves around.So let me get this straight: He TRIPLES HIS MONEY, EVERY SINGLE DAY, CONSISTENTLY, but it's not "fast enough"? At that rate he would LITERALLY be a billionaire within a few weeks.Literally anyone with a middle school understanding of math, or someone who's ever heard of the story of the grain of rice on the chess board would know that if you triple something every day, you would VERY QUICKLY end up with an outrageous amount of the thing you triple. But according to whatever retard wrote this movie, it's not "fast enough". Yes, becoming a literal billionaire in less than a month isn't "fast enough", and so he goes and takes a loan from a russian gangster.So he would rather risk getting murdered by a russian mobster than wait a few weeks to be a billionaire? This has got to be the stupidest and laziest excuse to provide drama in a movie ever. There are so many other ways they could have solved it. Like he could make less money. Maybe only have him earn 5% per day? At that rate you'd still make tens of millions in less than a year, but since he was in a rush due to not having anymore NZT, he couldn't wait that long?Or keep it as it is, he literally triples his money every day, but then he would VERY quickly attract the attention of the SEC and quite possibly also a few mobsters looking to shake him down for some quick money.But no, instead they go with the worst possible option. "Duuurrrrrrr becoming a billionaire in less than a month is too slow so imma go borrow money from a mobster hurrrr durrrr".It bothers me very much that nobody, not the director, the camera men, not the actors, or anybody else who was on set, bothered to point this out. Nobody who worked on this movie caught it. And they wouldn't even have had to re-shoot any of it, sinc him saying he was tripling his money every day was a voice over. So they could have changed it in post. This really pisses me off because i really liked the movie until that point. After that, it was basically ruined. I am simply not good enough at disbelief suspension to ignore a giant, gaping plot hole of those proportions. via /r/movies https://ift.tt/3mFrn4C
