You seem to know Diane pretty well. What's her excuse? :)
Are you sure that Cuchullain and his "hound" weren't actually combined and confused in the legend? Are you sure our version wasn't the true truth? :) :)
To be honest, I'm not that familiar with the Cuchullain legends, so I didn't double check Diane, Peter and Michael's version. Also I asked for some changes from their early drafts. They told me they had problems with some of the changes, so we compromised. (Or at any rate, we found something that I liked which they didn't object to.) Maybe they compromised too much, I don't know. But I do take full responsibility for what got on the screen.
Ultimately, I was the guy in charge of story, so the buck stops with me. I just wasn't aware we were making serious errors. I'm still not. Where did we go wrong, besides adding a gargoyle beast to the legend (a logical extension in our series)?
