Ok... just watched the film, but was pretty confused. Anyone know answers to the following questions? 1. Why did Neo have to return to the source? 2. How did he do that thing with the sentinels at the end of the film? 3. Why did the agents try to kill the keymaker, if he was part of the architect's plan? 4. How does the new Smith fit into all this? 5. What do you think is going to happen in Revolutions?
