Trust me, the game gets even more better as you progress.
As for the graphics:
I actually find them amazing. Everything is hand-painted and this just gives a unique and artistic feel to Divine Divinity.
I hope Original Sin feels like Divine Divinity. They've already brought back the reputation system, ability to interact with the world and murder anyone, let's just hope the turn-based combat proves to be an excellent choice rather than real time combat.
Either way, Original Sin is confirmed to have great dialogue, great quests (I can't even remember any fetch quest in any Divinity game as all the the quests seem to be composed of interesting story-lines and content) and a great story.
