Yes I saw that. UGH so horrid.
If the ship is giving him the information they needed to at least add a short sequence where the ship instructs him what to. How does he know the finger prints off of Zod's body will gain entrance to the ship? Why does he bring the body with him? The cutting of himself so that his blood is introduced is so off base. I didn't hear the ship tell him to do that and it needs to be there: have the ship actually say "the remains are in a state where the process will not succeed without the addition of living DNA." Then have Lex ask "can my DNA enable the process?" "Analyzing...yes your DNA is a suitable match". Give the viewer something! None of this sequence makes sense at all.
My point is Lex is supposed to be a very smart guy and in a position of power in the world due to the enormous wealth of his empire. Lex would never put himself in the ship itself, it would be a hired "expert" under his employ. The video shows the creation of a creature that isn't in any way under his control (in fact it tries to kill him and Superman has to intervene).
This video portrays Lex as a madman, and that isn't Lex Luthor to me. This video is exactly what I am referring to: Lex is badly written, and a strong deviation from the character in the comics and it is in this capacity that WB is failing: they need to stay more true to the character properties like they did with Wonder Woman.
