I do remember feeling something was wrong during my first go at 2, but I've recently gotten back to it and I'm having a blast. I think it might be the detection system? Guards spot you and investigate much sooner in 2, and that can feel frustrating and restrictive until you learn to take that to your advantage.
I'm doing a NL/ghost run and having guards spot me and come before the red bolt indicator is basically a free lure out of view of the others for a clean sweep of the area. Ether bottles and stinging bolts are also the shit.
But yes, the main draw is that the areas are really detailed and there's more ways to interact with the world and open paths/secrets.
Like in a mission, to rob a store you have to overhear a conversation explaining how to breach the vault - just an explosion won't do, you need three whale oil tanks, and the third available isn't just at the other side of the room.
