I've played the game through on Nightmare a couple times. It was a decent game. It is not as good as Dragon Age: Origins, but then the game was clearly designed to fit what a console could do, resulting in a dumbed down RPG. As long as you take the game as a new game, and not have the expectations of another Dragon Age: origins, it is a good game.
It may not be the most challenging game, but you certainly have to do more than hold down the right button. Clearly the guy is being dramatic. There will be a number of encounters that require a lot more micro management than that. Especially if you play on Nightmare difficulty.
The game seems to have melded a bit of Skyrim into the mix, making much of the game like a Sandbox game, but you can advance the story line when you are ready.
