I played the game at 1600x1200 with 2x AA. Still, the overall polygon count is relatively low and the levels don't show a great deal of detail. Texturing is sometimes bland as well (and not in the intentional way). The lighting is mostly well done, but then again, it's 2007 and every recent game has pretty good light effects.
There are NO facial movements except for ad-lib, non-sync lip movements, I just checked again. Nobody shows any kind of emotion, not happiness or sadness or distress, they've got a poker face going all along. The voice acting is good, I agree, but I dislike how most of the time you can't really tell who is talking, because they're all just standing around, looking uninvolved. They mostly don't turn their heads to the people they're addressing or make any gesturing.
And the level design, from a non-asthetic standpoint, is crap. You're running down hallways, i.e. there are "walls" closely to the left and right, intersected by "rooms", areas that are a little spacier, but still entirely and visibly restricted. And every few hundred yards, you make a u-turn and start going back the direction you came from - just in a parallel corridor. The linear feeling gets underlined by the fact that you can't jump, somewhat a trademark of console shooters, so sometimes there are obstacles of merely knee height. And there are even invisible walls, which I really hate, cause it takes you right out of the immersion and makes your brain go "What the f***?!"
I really like Jericho still. The athmosphere is great, horror fps are still an oddity. I think the body switching is very amusing and it gives a good makeover to the whole Die-and-Reload paradigm.
I just thought you were a little enthusiastic in your review, comparing Jericho to other games.
