There's a reason why most biopics shuffle events around, exaggerate or downplay things, and sometimes even misrepresent real people by slanting someone as a villain/hero. I really enjoyed the Robbie Williams biopic, ape and all, but they definitely made his ex bandmates from Take That look a lot more unpleasant to him than they probably were in real life; there's no mention at all of the fact that they did an entire song just for him - this one https://www.youtube.com/watch?v=JwC1Ctrj6Xk - essentially to say "we know you're feeling unhappy and unsure of yourself, but we believe in you!"
It's because real life rarely makes for a good story. Real life doesn't have big exciting climaxes that happen at the right time for a good narrative structure, and in real life when bad things happen it's not necessarily going to be because of a big evil villain who's got it out for you; it's just bad luck or your own bad decisions. I had my life ruined by a horrible person, but that person didn't do it because they were MWAHAHAHAH EVIL or even had anything against me. They did it because it was convenient for them to screw me over.

So yeah, even if it's "true to life", it's not going to work if it's just a string of "and then this happened and then that happened" until the book just fizzles out.
