GameTavern - Inception

Finally saw it. Based on all the articles and such littering the interwebs offering explanations to what happened I was expecting it to be a huge mindfuck. All I knew about the movie going in was that it had something to do with dreams. Turned out to be surprisingly straight forward. Still very enjoyable. I much prefer Nolan's non-bat movies.

The PASIV machine bothers me though. At no point do they explain how it allows people to share dreams. You're basically just injected with the drug to enter a controlled dream state; just connected to it by a tube in your arm. How does that allow everyone to interact with each other in the dream? A little tiny suction cup thingy on their temple is all I'm asking for.
