Well, we saw the "Pilot" episode, Storm Front, as opposed to the regular episode and I think the changes to Bob were important. Frankly, just sitting there and being witty just did not work. I get why they changed Murphy's name, but not ethnicity. Frankly, I just haven't met many Hispanic looking Irish people. But, Jim Butcher was on the set and helping make decisions...it wasn't as bad as what Lucas did to Star Wars.
