This is a title that even more payola reviewers seem to have found the cojones to actually slate. For once, almost everyone has spotted the emperor's new clothes.
This is a pretty-looking game, best experienced from a safe distance as a rather clumsy animation. It is primitive, facile and full of the "gameplay" tropes which mark out poor game design- the most notable of which is the QTE. It's a shame, an actual game that looked this pretty would be interesting.
If you want something with absorbing, slightly emergent gameplay, try DIshonored. If you want a clever, witty almost non-game that tells a branching story cleverly, try The Stanley Parable.
This does not avance gaming as a medium; far from it, this metetricious twaddle is little more interesting than the laserdisk games of yore, mechanically. The storytelling is not "mature", it's like a bad made for TV movie. Just mentioning "serious" themes does not get you a free pass if you do it with all the clunky awkwardness of Gordon Brown twerking.
It would be unkind to speculate on the judgement, motives or bona fides of the reviewer in this case, but I do wonder if there hasn't been a terrible mix up with which game was actually being reviewed, or a parallel universe.. :)
As PA pithily put it:
"Beyond: Two Souls is a mixture of a game that’s not fun and a story that’s not interesting"
