>>121063623I think the way the sheet looks so thin and so tightly conformed to Peter and Lois’s bodies in Family Guy screencaps looks weird and too still and stiff, making them look like cadavers with sheets over them. And then the camera angle is viewing them kind of clinically, and that doesn’t help.
For comparison, when Homer and Marge are in bed, the shot is usually from a more natural angle, and also their bodies usually aren’t as rigidly defined. It looks like Homer and Marge move around in bed, and like their comforter bunches up in places, more like the way real people look in bed.
