Pros
Pro Excellent free-flow combat system
Batman: Arkham Knight still uses the combat system pioneered in the very first Arkham game, but with various improvements. It is intuitive, highly responsive and supplemented with power-ups, combos and ability to use gadgets to add variety and depth.
Pro A pretty great story
Takes inspiration from so many areas of past Batman lore and creates a more interesting interpretation of a classic story. There's some pacing issues occasionally and it goes on a little too long at points, but is more than redeemed by a compelling overall plot, excellent voice acting, and interesting characters.
Pro Ability to drive around the Batmobile
Arkham Knight has the open world aspect of the previouc game but has now introduced the batmobile for use on the street with a full weapon loadout. Being able to drive around thee streets of Gotham as well as use the vehicle to take down bad guys makes for an exciting experience not seen in the series before.
Cons
Con Detective Mode investigation segments and the like are still boring and not good
Sometimes to push the plot forward the game will force you to do some "investigating," which basically comes down to a stupidly easy 'Where's Waldo?' minigame. It's not bad, but it doesn't really add much to the experience and feels kinda like a waste of time.
Con Lackluster, short DLC story missions
Don't buy the season pass unless you can find it on sale. It's not bad, but not worth an extra $20, and certainly not the $40 it cost before price drop. (FYI, you get a complete experience without the DLC - it truly is extra content, not main game content cut out and repackaged.)
Con Out of character for Batman to be killing enemies with guns on the Batmobile
Batman has never been a character that kills people, especially with guns. Seeing that the game has core gameplay elements where Batman is mowing down badguys with the guns on his Batmobile, it is really out of place and breaks immersion for those that are familiar with Batman lore.
