Plenty to do and a great story (No spoilers)
After the first part of the game there is a scene where batman is on a rooftop. I found myself looking over the city with my mouth open. The game looks so beautiful, gritty and realistic it's amazing.
The gameplay is fantastic. You practically feel like Batman playing the game. Gliding around the city is amazingly fun and fighting hordes of people is very fun and entertaining. Everything you loved about the first game is polished and improved in this game. E.g you can now counter 2 enemies at once which is fantastic.
Overall, this game is one of the best I've played. Super realistic Graphics, very fun and entertaining and an amazing and shocking story.
