I don't know what's going on behind the scenes, but it almost feels like artists working on these are being forced to draw in a certain style. That stiff, lifeless, traced-photography look... It's as if getting the resemblance right comes before the storytelling.
Now, I realize how hard it is to draw comics, so I'm not knocking these guys. The effort is appreciated. But I wish they'd hire artists with different, distinctive styles and just let them go nuts with it, interpret the characters (visually) the way they want.
