>>3 I know, right? I don't get why people had such a hard time understanding it. Sure, it isn't the kind of movie you can watch while really concentrating on something else and still be able to follow what is happening. But I would definitely not classify it as a mindfuck.
>>4 Yes it did, but that's not important. Notice how Cobb doesn't even look at it, doesn't give a shit whether it falls or not? That's because he is sure this is reality and that those are his real kids, spinning tops be damned. And that is all that matters, isn't it. He got his happy ending, he got to come home.
And there are loads of other things that point toward the fact that what we were told was reality, was in fact reality and not a dream. Like, Cobb only wears his wedding ring in the dreams and he doesn't wear it at the end, or that the actors portraying the children at the end are different, older actors wearing other clothes than the ones we've seen throughout the movie.
