I'm used to seeing Light Yagami as a long and lean character, so I didn't recognize him right away. But yeah, this does look like him, especially with the sweeping bangs. I like the title, too, since Death Note didn't clearly delineate who was the bad guy and who was the good guy. It made the viewer think, and that's what I loved about the show.
Was he? He only killed hardened criminals who were malignant for society anyway. Perhaps he saved innocent lives by killing them. The fact that it's debatable, and not cut and dry like so many other shows, is what I loved about it.
