Inception Revisited - Second Viewing

Watching it a second time was even better because there's more understanding now than the first time. A lot of things are clearer which made it even more fun to watch.So here's a few more realisations.In each layer, there has to be a dreamer, to "anchor" the rest of the dreamers. But the subject does not have to be the dreamer. It can be anyone else's though I'm still unsure how the subject was determined through what process. But it will be the subject's subconscious that populating the dream. Concluding that, and referring to the previous mentioned article, that the actor Rao has no idea what he's talking about on the third layer. It was indeed Eames' dream, but they made it look as if it's Browning's just to fool Fischer.As for the layers, I've deduced that there are only four, including the limbo. Reason because when Cobb and Ariadne went to get Fischer (who died and descended into limbo), they "dreamed" their way down instead of dying. So there can only be four layers in order for it to make sense... unless Nolan messed it up himself.As for how the dreamers could have survived so many attacks without getting injured, I came up with this explanation. When we dream, we don't die that easily no matter how dangerous the situations get. So same here. Especially when you put the dreamer to control the dream, the dreamer can almost always overcome the adversaries. So this would make perfect sense instead of being another James Bond antics.But on this second re-watch, there are more flaws as well. Like how Arthur was supposed to only have a few minutes before the "kick", but there was no way he could have done all the tying up of "loose ends" and re-fixing the explosives and blowing up the safety of the lift in those few minutes. Impossible.And one of the biggest flaw was how could Saito be so old at the end when he didn't go down to limbo too early. The age difference between him and Cobb was too huge. Nolan messed this up just to get the dramatic effect.Even though I understood a lot more after the second viewing, there are still a lot to understand fully. I think I need to watch a third time...
