Visual first impressions are dangerous in video games; it's not uncommon for a developer to strategically position their best content in the beginning, only to fall apart hours in. And Divinity: Original Sin's first impression from a visual standpoint is deceptively unassuming. It's got its own art style and its own perspective, and its HUD is loaded with details and the classic action bar. Lesser fans of role-playing games will be instantly turned off, but if you count yourself among those, push onward. While Divinity: Original Sin isn't a technical showcase by any stretch, it is a great-looking game. For all of its complexity, the user interface is attractive and navigable; this is a very important positive, as you'll be spending more time messing with your inventory than in most modern role-playing games. But in action, Divinity: Original Sin looks great; environments generally stick to well-established adventuring tropes, but they remain a joy to explore nonetheless. On top of that, it has some of the most viscerally satisfying action I've ever had the pleasure of witnessing in a turn-based combat system.
Divinity: Original Sin - Enhanced Edition's sound design trumps the original release in its voice acting. Not in its quality; having played the original release, I think there might have been some changes -- and not all for the better. However, I can't deny that the amount of effort has increased significantly. Non-player characters whose speaking roles were reduced to simple text boxes have voices, now. And while the results are mixed as a whole, it's still an improvement over silent characters. I have no complaints whatsoever with Kirill Pokrovsky's excellent soundtrack.
