Inception

[Vivisteiner]

(SPOILER)
Reasons why the ending likely was reality:

1. Cobb and (possibly) Seito otherwise magically teleporting onto the airplane, so a dream would be contradicting everything we were told in the movie.
2. Seito not being an old man when he "woke up." Though this could be explained by both Seitos being a projection, which would be consistent with the dream theory without contradicting everything.
3. The top wobbled for a split-second, and so a dream would be contradicting everything we were told in the movie.

(SPOILER)
1. I'm not arguing that there's some kind of magical teleportation. Instead I'm arguing that Cobb proceeded to kill himself in limbo. As a result, because he was still under the sedative, he would have probably just gone into a deeper dream state instead of returning to reality. In this dream state he created projections of his fellow team members.

2. The reason why Seito is young at the end is probably because he is a projection of Cobb's mind and not the real Seito.

3. A wobble doesn't mean that it was going to fall. And anyway, the top only reflects Cobb's belief as to whether he is in reality or not. If the film started inside a dream, what happens to the top is meaningless as it's merely a creation of his mind anyway (and so it only reflects his mind, not reality).


Overall I thought the ending was excellent and it really made you reflect on what was really going on. It opens up all sorts of alleyways of thought and by consequence a vast array of interesting discussions.
