Horribly missed opportunity to do something interesting.
This is an excellent description of DAII as a whole. In fact, the saddest thing about it is how much potential it had.
For example, I vastly prefer the idea of DAII's campaign to DA:O's save the world by killing a dragon. As someone already said, Darkspawn are boring: mindless monsters you need to kill. Mages vs. templars and Qunari vs. the rest of the world offers a potentially far deeper story by asking who do you need to kill and why... But of course it all goes to hell if you decide to cut the Gordian knot of moral ambiguity with a magical sword made of bull****ium. (And it doesn't even come in three different colors, it's invariably red.)
But as for the party, I wouldn't say all characters ended up completely bland and boring. It is of course a rather subjective thing, but some of them had a lively feeling DA:O's party usually lacked.
This post pretty much echoes my own thoughts about DA2. I've actually been playing through it again recently, and despite the endlessly recycled environments, I still enjoy it.
I find it odd that the sarcastic version of Hawke is actually probably one of the most unambiguously good characters in the game - more so than the "heroic" Hawke. And much funnier. Call it cheap laughs if you want, but Sarcastic!Hawke, Varric (whom I actually like immensely as a character), and Isabela make me laugh just as much as Morrigan and Alistair did in DA:O.
It did have a lot more potential (Kirkwall is a really, really ugly city) that it showed, but I like that it's a more personal story than DA:O, which at times can just feel too big. Kill dragon, save world, blah blah blah. Hawke is trying to make the best out of a crappy situation and just keep his/her family together.
I expected Leandra Hawke to bite it at some point in the story, but the way it was done was just so BRUTAL. Also, my first playthrough, I didn't know that I shouldn't have taken Bethany along to the Deep Roads and I wound up having to kill her. Ouch.
If they can keep the character charm and correct even some of DA2's major mistakes, I'll be tentatively excited about DA3.
