Yes, it is as good as DD, and you can turn into a dragon (well, wyvern, technically).
Divinity 2 switched to a third person perspective camera, which can be zoomed out to an almost isometric perspective or zoomed in (along a curved path) to an over the shoulder type view or even past the character to look up.
Quest design is better in Divinity 2, though world interaction is less (due to the camera change there is no mouse cursor during gameplay, just when paused and in menus, etc). The music is similar; the humour is better, though there are not as many easter eggs as DD. The world design is much less flat.
The only DLC in the original Divinity 2 releases were equipment sets, which are available in the game or through the Developer Mode cheat window in the Developer's Cut.
