When you're at home watching a movie, it's easy to armchair gunfight. For instance, you might point out how stupid it is for a henchman to watch his friends get beaten to death while waiting for his turn to gently attack. But that's not fair to the henchman. Unlike you, he has no idea what a Steven Seagal is.
The point is, you can't know what went into a movie character's bad decisions. Still, you have to question why ...
6Mance Rayder In Game of Thrones Refuses To Use His Magical Bird Spy
In the frozen no man's land north of The Wall, Mance Rayder manages to unite every wildling, hillbilly, wizard, and giant into a massive army. To get that many lunatics to come together about anything takes cunning and leadership more fantastic than all the show's dragons and tits combined.
And he can also totally pull off a stray-cat jacket.
Rayder's plan is to kill his way past the Night's Watch, but he's told by super-secret spy Jon Snow that there is an unstoppable army waiting for them. It's a lie; the Night's Watch is actually a sad-eyed fat guy and 40 cranky convicted sex offenders. The lie is crucial to Jon's convoluted plan to stop Rayder.
Here's what's stupid, though: Mance has a guy on his team, Orell, who can take over birds with his mind. No one wants to have him jump into a bird and go check things out? Even if everyone believed Jon Snow that each castle was manned by hundreds of well-trained soldiers, why not take a peek anyway?
"I could bird warg and be back in like 20 minu- Oh, the new guy gave you some intel? I guess I'll sit my amazingly magical ass in the snow and do NOTHING then."
Maybe Mance is a better community organizer than he is a military tactician, but here's how the dumbshit chooses to handle the situation. He sends the guy who can scout as a bird on (human) foot with Jon Snow, the least-trusted guy in his army. Sure enough, Jon kills him. It's as if Jon Snow's entire plan was to do such obviously obvious things, no one could possibly see them coming.
