In my opinion, gameplay>graphics, graphics are just there to show you what's in the game world, because if you can't see a thing, then there's no reason for graphics to even exist (you could better sue text instead).
If i can't see anything because it's full of motionblur, overused bumpmapping and hdr, then the game has bad graphics even if it runs 5 bizillion polygons smoothly...in contrast, starcraft 1 (a 2d game from over a decade) still has good graphics, because it has enough details to be believable and realistic and you can see what's going on on the screen all the time and you never look at a unit and ask yourself what that thing is supposed to be.
And actually, i think cell shading is a good way for indie game studios to give their players nice graphics without the 100 artists and the 1 million budget big studios have...
