Star Wars my friend, all of them. I watched all the 6 parts, for 6 times and every time I watch them, I find something new and deeper. Its also movie that triggered one or two big paradigm shifts in my life, and it also helped me make some more mature decisions in the past.
Note: Interesting thing I noticed the last time i watched part 3: Revenge of the Sith.
The moments after Anakin chokes Padme. He says to Obi Wan:
U are either with me, or you are my enemy.
To that Obi Wan responds.
Only a Sith deals in absolutes. I will do what i must.
U can try incooperate that in the Graves model
