I personally find it extremely overrated. Not to say that it's bad, but it's hardly the best story I've ever seen (although it is a good one with fairly believable characters) and, as has already been said, the gameplay is. . . well, point-and-click with lots of QTEs, what little I've played anyway.
All in all, it's a decent whatever I should call it (I find it more akin to an interactive novel than a "game", by standard definition, anyway) with a fairly good story and well-written characters.
