That's pretty much how I felt about Byron. The actor is a nice enough guy, though he drinks waaaay too much. But I never once cared about him. Any charisma he may have had was overwhelmed by the arrogance he exhibited towards people who had done him or his own people no wrong. There's no denying the plight of telepath discrimination, but still.... about the only time I sympathized with Byron was when Bester was around.
Bester made me sympathize with Byron less, personally. I mean, Bester's a character you hate, but you can't deny that he's charismatic and has the power of personality. Byron is supposed to be the same, but it just isn't realized.
And what's that about Robin A Downes (misspellings entirely my own) drinking too much? Bad con experience?
