This is an incredibly high quality, fucking hideous model. Everything they did to Alyx flies in the face of her character's representation. Gross.
I'm one of those weirdos that thinks that HL2 has fairly timeless graphics. That game was constructed with what call "functional graphics". I don't mean functional in the sense that they just get the job done, I mean functional in the sense that everything that is represented graphically has actual function in the game. All of the terrain and objects have collision that is native to the representative/graphical model. All of the set dressing is movable and manipulable, which means you don't end up with the weird dichotomy between what is "game" and what is "just visuals".
For instance, when you walk into a room in Uncharted 2, all of the chairs and tables are nailed down, if you shoot a gun at a pot, it doesn't move...the only thing that is gameplay dependent are the specifically noted items that the designers have laid out for you amongst the breadth of set dressing. Everything is gorgeous, and everything is made of concrete.
Whereas HL2 has relatively spartan environments, but you know you can interact with literally everything in the scene. This means the user doesn't have to split "what is there to look good" and "what I actually can play with" in their head.
Most games look beauteous, but they fall into the Uncanny Valley of environments.
