A company being excited for their new game is a huge slap in the face to all the fans that liked their old games.
It had the shell of a Metal Gear plot but no filling.
Weirdly enough the most apt analogy is fan fiction. MGS V seems kind of like something you'd get in a mainline release, but lacking the detail, quirk, and identifiable character.
I think all that plus the way the game is laid out give the player perceived ADD.
There's no way to follow a story this bland and dense stretched across 50ish episodes.
