Batman: Arkham Knight Review

I've spent quite a considerable portion of the last two weeks playing this game and have managed the following

1. 100% of main game
2. 100% of new game +
3. 100% Red Hood Pack
4. 100% Harley Quinn pack
5. 9/9 stars Scarecrow Nightmare missions

To do a review justice, I will have to talk spoilers eventually. But I'll discuss gameplay first for those who don't want spoilers for the full game
