Just like every one of our ex-lovers, some movie characters have to keep secrets if they know what's good for 'em. When done well, a character with a secret builds drama, drives the plot forward, and occasionally wears the hell out of a sinister mustache. Most times, though, movie characters refusing to be honest and open with each other results in nothing but pointless filler and frustrated audiences. For example ...
Buzz Lightyear Doesn't Think He's A Toy, So Why Won't He Talk To Humans?
The Toy Story series posits that all toys are secretly alive, and only pretend to be inanimate objects in the presence of humans. This interestingly also includes the spaceman action figure Buzz Lightyear. Uniquely, he doesn't think he's a toy, yet he still acts lifeless when his owner Andy wants to play with him.
Maybe he's shy?
Why It's Stupid:
Throughout all three movies, Andy proves himself to be a considerate, loving human being. There seriously should have been a point where his toys said "Screw it" and revealed themselves to him as sentient beings.
"So did you guys watch me ..."
"Yes, every night."
They could have been even better friends! But more importantly, Andy's neighbor Sid takes great joy in destroying and "rebuilding" his toys, yet none of them have ever cried out in pain and/or horror at any of it. They played dead "just because," and let a mad god transform them into Cronenberg masturbation material. Why? Honestly, the only answer seems to be that the plot called for it. And because Toy Story is secretly a love letter to nihilism.
Sector Seven Keeps Megatron's Corpse A Secret In Transformers For No Apparent Reason
Sector Seven is a shadowy government agency that popped up in the first live-action Transformers movie. They possess the frozen body of Megatron, which is the source of all modern technology, and had been hiding him away behind the Hoover Dam for decades.
"We've been using him to chill our beers." -- Sector Seven, probably
Obviously, Megatron's minions eventually infiltrate the base, unfreeze their boss, and allow him to escape. That's what good minions do.
Why It's Stupid:
According to a Sector Seven top honcho, Megatron wasn't guarded that well because he didn't pose a serious security threat. But the movie starts with a military base being attacked by robots that look a lot like the guy they have in their giant fridge. The secret agent people should have taken one look at those reports, connected the dots, and bunkered down like their name was Archie, because something was obviously looking for their alien popsicle.
