1.渡边谦并没有看到对富二代最后的inception，就死在了第三层梦中，继而进入limbo。问题是，他从limbo回到现实（飞机上）之后，在没有确定inception是否成功的情况下，为何就直接打电话给有关部门了？

退一步，即便渡边谦确定了inception成功，也应该在富二代拆分了公司之后再实现对cobb的承诺才对。

2.第一层梦境中的众人自由落体时，第二层梦境中的人会失重。那么，为何第二层梦境失重了，第三层梦境没有失重？

从物理上说，一个物体位于自由落体（free fall）时的受力状态和失重（zero gravity）是完全一样的。

3.kick（刺激、穿越）的条件到底是什么？根据片中人物的对话，应当是人在自由下落时，内耳或中耳（只看一遍，记不清了）感受到失重的一种刺激。

如果是这样，那么：1）第一层梦中面包车下落的整个过程中，里面所有的人都一直处在kick的状态，而不是“面包车冲下栏杆”是第一次kick、“面包车接触水面”是第二次kick；2）第一层梦中面包车的下落过程中，第二层梦中的人都处于失重状态，实际上也一直是kick的状态。

4.关于arthur在第二层如何造出kick的解释如下（http://www.cinemablend.com/new/Inception-Explained-Unraveling-The-Dream-Within-The-Dream-19615.html）：

Arthur blows up an elevator to create a Kick in anti-gravity. How does that work?

A: Since there is no gravity, Arthur disconnects the elevator from the cables and then uses an explosion to propel it, as it would be propelled if there were gravity. When it hits the bottom they're shaken around, creating a Kick. Arthur uses the elevator because he needs a way to insure that the Kick occurs quickly and to everyone at once so he doesn't have to do them one at a time, in much the same way the falling van drops them together.

"When it hits the bottom they're shaken around, creating a Kick."难道shake around是kick的条件？

5.还有一些疑问，比如面包车的第一次kick为何没能使arthur醒来等等。。但是由于只看了一遍，可能自己没看清，以后再研究吧。

关于面包车的第一次kick为何没能使arthur醒来，cinemablend.com的解释并不能让我信服（http://www.cinemablend.com/new/Inception-Explained-Unraveling-The-Dream-Within-The-Dream-19615.html）：

Why didn't Arthur wake up when the van drove off the bridge?

A: When the van drives off the bridge, Cobb says they missed the first Kick. This is understandable since Cobb, Eams, Ariadne, and Fisher Jr. are two levels below it and can only be awakened by a kick in the level above them, where Arthur is. But Arthur is in the level directly below the vans, and the rules of the movie do seem to suggest that he should have awakened by that Kick. Perhaps experienced dreamers have some control over whether a Kick wakes them up? We're a little baffled by this one, let us know if you have a better theory.

Alternate Theory CB reader Jordan offers this possible explanation: Ealier in the movie Arthur tells Ariadne that if Yusuf kicks too early then they won't wake up. While normally in order to wake up you must recieve a Kick in the level above, this isn't true when using the special sedative. Instead with the sedative it takes two synchronized Kicks. In order to be Kicked when under the sedative you had to be kicked in both levels simultaneously. Arthur didn't have the second Kick ready when the van drove off the bridge, so he wasn't awakened by the van falling off the bridge.

最后对影片的感想：

牛X之处：关于多重梦境的想象力很牛X，非常牛X。

不足：架空的规则太多，匪夷所思的剧情并不是由一个简单的规则推导出来的（反例：致命魔术，规则只有一条：存在一种复制机）。

结论：硬伤是必定存在的，但不影响对它5星的评价。

。。牺牲了整个午睡时间写了这么一大坨字，希望以后都能被解答。
