Polygon's review is my favorite:
With Beyond: Two Souls, Quantic Dream has smoothed away nearly all the rough edges in how it presents its stories. The other edge of that sword is that it lays the stories themselves bare to be judged entirely on their own. With so many of the traditional elements of gameplay stripped away, like challenge and exploration, a tremendous amount of weight is put on Beyond's story to carry the day. While it's exhilarating to see a team that has worked so hard to perfect a new way of telling stories, I couldn't help wishing they had a perfect one to tell.
