I thought the blood looked terrible, it looked like it was painted on, the blood looked fantastic in the middle of act 3 in that bloody and chainsawy section.
That first level was not great in terms of gameplay, but I will give you it did look good, though the death stuff was not great (I would know)
The caverns do look impressive as does the water, but I still don't think it can match Uncharted. No moment in Gears 2 (upto start of act 4) has compared to that moment in Uncharted when you are behind the waterfall above the U-boat in chapter 3 (I think) for me.
Also, while the first levels had colour, it has been getting a bit grey, and while there was some respite for snow, it is back to grey. Playing Uncharted with the nex-gen filter turned on makes them look the same
In terms of detail I can't comment because I am playing on an SDTV, and not sitting 1 inch away, but the game does look fantastic, even if it not the best looking game ever
