Sorry to bump this but i finally watched it last night.
The movie is still kind of a mess, i have not seen the assembly cut mind you, but i feel like all the stuff added only slightly improves the movie, it gives a little more depth to everything but seems like all the issues it has are not solved by adding footage.
I think the theatrical cut is the best version, as flawed as it is. Maybe with some little stuff added from the other cut but overall it needs a better script.
