The Banff World Television Festival, June8-11, snuck by us with all the David Boreanaz in Monte Carlo TV Festival pictures and hijinx, but Hart Hanson was there and he said a bit more about the plot choices. He's not backing down from his right to oust Zack but he is willingly admitting their errors in how compressed the plot line was in the end. You can read a blog post here from blogcritics.org about various producers/creators on different shows, including his. But I've also copied his excerpt for you here.
As for the fate of Zack (Eric Millegan), Hanson was apologetically unapologetic. He believes in the creative choice to shake up the ensemble, indicated that because they hadn't killed the character, the door was open to revisit Zack "with his poor hands in black gloves or something," but admitted that the strike-shortened season made that arc too compressed. "It should have been seamless. We failed. There are no excuses in television. We should have found a way to make it land more elegantly."
