So she curses the kid; on her 16th birthday, she will prick her finger on the spindle of a spinning wheel and die. Nice, curse a baby because her parents snubbed you, probably because you shit in the punch bowl once. Your name's Maleficent, for Christ's sake.
So Merryweather, who apparently is not as powerful as Maleficent (evil is always stronger in these things. Great message for the kids.) tweaks the curse so that the girl won't die, she'll just go into a coma until the man who loves her gives her a smooch. Remember this; it's important later.
So what do you think her parents do? Sit on it for the next decade and a half and then work on protecting their kid? Maybe help her find that special someone (they had already arranged her marriage to the kid from the next kingdom) so she could prick her finger and then immediately get a kiss? No, those would be simple solutions that a non-idiot might consider. Instead, they do what any reasonable parents would do; they order every spinning wheel in the kingdom burned (how many livelihoods did that destroy?) and send their brand new baby daughter out to the woods to be raised by the faeries that were already not strong enough to stop the evil one in the first place.
The three faeries then proceed to raise her to be afraid of any and all strangers until it is time for her to go back to the kingdom and become the princess and marry the prince. On her 16th birthday. Now, think about this for a second; the curse says she will prick her finger on her 16th birthday. Not the day after, the day of. So why not wait 1 day? Nope, bring her out of hiding the fucking second she is actually in danger. They had 15 years, 364 safe days leading up to that day, and the rest of her life after it.
This is like going back in time and telling everyone involved with President Kennedy's drive through Dallas that he was going to get his brains blown out, they believe you, and wind up closing some libraries and sending him out anyway.
Sorry, dude. It turns out that a kiss from Marilyn Monroe would have stuffed your brain back into your melon. Guess you should have rethought that whole "shutting her up" thing.
So they wheel her out on the day she is fated to almost die (but not really) and Maleficent finds out and lures her into the castle tower and, because the girl is in a trance, makes her prick her finger on a spinning wheel she conjured out of nothing. Hmm. Seems like hiding her for her childhood was kind of a waste time. Maybe if they had waited one fucking day, that would not have happened. Shit, they could have lied about what day her birthday was and the evil one's plan would have been fucked. Apparently, the kingdom was slaved to stupid.
But don't worry, to spare the parent's grief of their daughter being asleep until they could find someone who really liked her, the good faeries put the entire kingdom to sleep.
What?! Wait, hold on a second. You mean to tell me they can knock out an entire country, but they can't lift a curse? So they find out that the princess has indeed found a true love and it's the prince she was arranged to marry. Sweet! But he's been captured by Maleficent. So no biggie, the y just teleport in and free him.
What the fuck? They can teleport? And they give him a magical shield and sword. I think they were holding out the whole time. Either that, or they spent the princess's childhood in the woods killing boars and gaining XP.
So the prince rides to the sleepy kingdom to give the princess a kiss, and Maleficent shows up and turns into this:
Wait a godamn minute.... What was that shit with the spinning wheel? She clearly was acting purely out of spite, why not turn into a dragon and bite the princess in half? If you wanted to crush the parents emotionally, I think bisecting their kid would do that.
You can see how this all worked out; the entire story is filled with dilemmas with a clearly right decision and a clearly wrong one, and they all choose the wrong one. The prince is the only non idiot in the whole thing, once he is done being fucked with, he simply goes and stabs the dragon, kisses the girl and saves the day.
Instead of "Sleeping Beauty", it should be called "The Prince in the Sea of Stupid."
