The ending of Inception was left for each person to come up with their own theory of what happened, did it fall или not? Was he back или was he in a dream?
For this reason, I don't think there will be another Inception unless it was based on a whole different set of people (and they'd have to look REALLY hard to find a cast even half as good as that).
i seriously doubt there would be a second. the end was a cliff hanger. so if there is a секунда one. it would not allow people to figure it out for themselves and for them to drive themselves crazy..
I don't think there should be a sequel. It is too often that sequels are no where near as good as the first movie, and Inception was just too phenomenal to risk a секунда movie taking away from its quality.
