I agree, Evanus got it mostly (imo) right otherwise: the ingenious use of meet Walter for the creation of David, the opening with the tears welling in David's eye as the black goo drops on planet 4 with the sound of the wind (Chills), the flashback parts perfectly placed(Chaos edition not so well), Advent I would have stuck before the credits but I forgive it
The Chaos edition is great to include Phobos
And Last Supper but it suffers including Stuff like Oram and Lope's video logs which drag, Tennessee's is entertaining and Daniels is kinda key to the story but I felt something flirting with 3 hours was beyond even a prequel nut like me
