I'm not putting the tags because of the title. If you clicked here and haven't seen, too fucking bad.
Just managed to catch this last night. Koreans are batshit crazy about booking ahead...by like days. I got lucky.
Pretty kickass movie, I'm sure it's cliche by this point to discuss it but oh well. Not as complex as it could have been, but I had a few questions in regard to the plot:
How did they "connect" people in shared dreaming? Wouldn't that require a neural interface (a-la-Matrix) rather than just a forearm IV? I wish they would have gone more in-depth to the theorized Army invention they just mentioned in like one scene, seeing as how it's the basis for the entire movie.
Is a 4th level dream the same as Limbo? How did Cobb and his Wife get to Limbo the first time, by delving too deep into a dream? When Saito dies, he goes to Limbo....but then Cobb and Ariadne (Juno for all intensive purposes

) are able to get to Limbo by going a 4th level in? That didn't make sense to me.
