The cgi the cgi oh no.

This talk about the cgi is ridiculous for 2 reasons.

First this was intended as just a free bonus for people who pre ordered the special editions of halo 5.

Second it's stylized, it's not meant to be photo real or Pixar quality. Why? Cause it was A FREE BONUS FO4 PRE ORDERED GAMES.

It was only released to the masses due to fan demand. Just be happy you got to see it at all.

If you want the full story read the book. It's much better than the movie anyways. Much more story.

If you REALLY want to get into the story you need Dr Halsey's Journal which was special feature from halo 3. It's a litteral diary full of story elements, pictures, post cards, schematics from the Spartans armor, info on the Spartan program, her thoughts, the design of Cortana etc. Excellent book but never sold seperate so good luck.
