Now my turn ... hee hee ...

What I thought is good?
-- 3 memorable scenes
(i) the doorknob scene
(ii) the hearings scene with the Senator
(iii) the plane crash scene
-- The performance of ...
(i) Leonardo DiCaprio, Cate Blanchett, and ... * drum roll * why few (if any at all) mentioned Alan Alda (Senator)?! Alan Alda was VERY good. ;)
-- The set and the costumes

What I thought could be better?
-- I do NOT mind a 3 hours movie, but I thought the screenplay could be "tighter", and if I am NOT too ambitious, the 3 hours (or even 3.5 or 4) could highlight more about his childhood or his old age ... * greedy *

In sum, worth watching.
