Judging from what I've seen, anyone who claims these is an incompetent moron.
Seriously there's a whole underground waterfall thaig to explore ... and a dozen unique dragon fights we know of.
The fact of the matter is, if you judge a Dragon Age game by the first 10% of it, you're doing it wrong.
Underground waterfall thaig? Here's what they'll say:
"While the environments are relatively pretty and take advantage of the Frostbite engine, there's no interactivity - you can't jump, sprint, or traverse the environment in any way. In a post-Assassin's Creed and Uncharted world, that's becoming increasingly unacceptable"
Numerous unique dragon bosses? Here's what they'll say:
"There are plentiful bosses, and they are quite difficult, but beating them essentially boils down to buffing up your party and just hammering away at them, remembering to quaff potions every now and then. There are no unique tactics involved, and I found myself dreading the boss fights because of the tedium involved, or even lowering the difficulty to Casual just to get past them"
