It took some time, since people were still playing through the game I think.
And also, we don't know how much time it takes for a new review to be added to the game's page.
But there are some reviews now:

I usually don't do reviews, but when I decide to do it, I finish the game first.
Fahrenheit for example, would be a game I would give a good score, if I hadn't played it to the end, and seen all the crappy things that happened.

Because it started well and stayed good for quite a time, it really looked that it was a good game. But if you play or see a playthrough to the end, you'll see it goes downhill.
It's not like Portal for example, which is good from the beginning to the end, and I definitely wouldn't give it 5 stars, it was a disappointing game.
