This movie NEEDS an extended cut
Even though I liked it, I had the feeling that the movie was playing a x1.5 speed the whole time. There's too much happening, too much story, and it seems that Nolan cut off every non-essential part so the movie fits in a 2.5 hours mark.
In my opinion, this movie needs at least an additional hour. Mostly, it needs to slow down, it needs to give some air, some breaks. With the current editing, it's too much, too fast.
Definitely, it would benefit of an extended cut.
