Funny to hear how much you guys dislike the casting......as just last night I was just listening to TV critics Andy Greenwald & Chris Ryan (RIP Grantland) discuss this series, and both of them were raving about how brilliant the casting was. I tend to agree, but it wouldn't be art, if it wasn't subjective.
Aside from Travolta I can't think of anyone I'd recast personally.....and even with Travolta, no real realistic options immediately come to mind that I'd prefer to see in the role. Once I got over the "Travolta doesn't look like Shapiro" element, I found it to be a really damn interesting performance. I'm kind of glad he's in it, as I'm now looking forward to seeing what else he does with the role as the series progresses.
Goes without saying, but Vance will obviously be the star of the series.....(creators obviously know that too, given they have him in first episode, despite him not joining the defense team for quite a while later in the timeline).....will be good to see him getting some well deserved recognition with this role.
