I'm about 7 hours after completion of the Deep Roads which I guess is considered Act II?
Anyways, at this point there still is no story, no villain, no central theme other than doing chores for people. Just hit level 15, my guess is I'll finish around level 20-22 and I'm shocked at how little there is to the story so far. I've gotten my house back....is that supposed to provide a compelling story arc? Is this a satire of the mortgage crises? (j/k

)
I don't find my companions particularly compelling either, in DA I wanted to talk to my companions, especially Morrigan, Shale, and Sten. Earning their trust and respect is something I wanted to do, I could care less about most of these chars in DA II, especially Fenris and Anders what a couple of gimps.
I rerolled my skills/stats yesterday to try out a few new things like Stealth. Since the combat is so fast and furious, it's pretty useless. Sure there are a lot of attacks that get bonuses but I crit so much as-is it's just not practical. The same thing with Evade, in the rare instance where I encounter a boss that likes to hit hard and spam knockdowns, both are useless because they'll be interrupted by the boss spam. Against lesser bosses and normal mobs they're useless because they go down in seconds. So I'll be rerolling again and going for pure damage.
