ELI5: How do movie 'flops' ever get released?

Movies all seem to take a good few years to go from initial detail to actual release in the cinema, how could it go so wrong, with nobody intervening along the way? (e.g. Jack the Giant Slayer)

Imagine if you put 30 hours into an assignment and read it and you realize that it's shit, but you either fail to turn it in and the teacher gives you a big fat zero and writes you up or you turn in your shitty assignment, maybe get a bit of bad rep in the teacher's eyes, and at least get any grade at all (maybe you flunk narrowly or get a bad but passing grade).

You can always do a better assignment later on to make your teacher change his or her opinion of you, but if you don't turn it in, you'll have wasted 30 hours, gotten a zero and been written up t the principle, all at the same time.

Even simpler, $20,000,000 spent on the movie + $5,000,000 made on the movie from stupid weekend moviegoers who didn't have anything else to watch is a $15,000,000 loss, whereas $20,000,000 spent + $0 due to a no-release means a $20,000,000 straight up loss + you get a reputation for being a guy who can't deliver a finished product.
