READING 1: Saito hired Cobb and co. to plant an idea in Fischer's mind. They succeed, and in the end Cobb really does go home to his kids.
READING 1A: Saito hired Cobb and co. to plant an idea in Fischer's mind, but the endingeverything from the moment Cobb "wakes up" on the plane until the credits rollis just a dream.
But if he is dreaming, where exactly is Cobb supposed to be? Is he still in limbo? In a deeper realm of limbo? By what mechanism did he get there? (In other words, what happens immediately after the aged Saito reaches for that gun?)
Meanwhile, a commenter on CinemaBlend notes that Cobb appears to wear his wedding ring in all the dream sequences, and only in the dream sequencesbut he's not wearing a ring in the final scene. This suggests that Cobb did, indeed, go home to his kids and the real world.
READING 2: Cobb is actually the subject of the inception. At least somemaybe allof the "real world" scenes are actually dreams.
Dileep Rao, who plays the chemist Yusuf, doesn't buy it: "[You're] saying it's like some sort of crazy-ass psychotherapy session where the whole thing is a constructed narrative of massive complexity only to distract Cobb so that he will achieve his change? I mean sure, you could totally say that that's what it is. In a way, that's what we're doing to Fischer, so it's not unfounded. The problem for me is that you're using negative evidence to support a story that isn't there. I don't know what to say about a character who only exists before and after the movie. ... I mean I don't know where that kind of speculation ends. It's like people who are convinced 9/11 is an inside job."
READING 3: Everything we see is a product of Cobb's subconscious.
Boring
READING 4: Inception is an elaborate metaphor for moviemaking.
True no matter what the story really means.
