To the extent that "Arrow" is a weak story, I can't blame Grell. He's producing the comic book adaptation of a lame-ass CW show. (Full disclosure: To my chagrin, out of curiosity last week, I watched the pilot episode. It sucked. Spare yourself.)
On the other hand ... he's producing the comic book adaptation of a lame-ass CW show.
I'd rather he wrote and drew his own projects, stuff like JON SABLE from earlier in his career. But he's got bills to pay. I understand.
The art Grell posted on his blog looks OK, though to me, it's pretty much just the same archer-against-an-urban-landscape poses we got in the 1980s with the middle-aged Green Arrow. I dunno. Maybe there's only so many ways to stand there scowling in a hood while you pull back on your bow.
