Unmitigated disaster? Really? I'll be the first to admit that the second half dragged on, and it relied a little to heavily on character stereotypes, but there's absolutely nothing in either the casting, or general show concept that made me think "There's NO way this could be turned into a good show". It is a GOOD foundation. Not great, not like the BSG miniseries, but that's a rarity. Pilots are works-in-progress and should be seen for the potential as much as the actual content.
Even by itself, it's entertaining.
He didn't say it was an unmitigated disaster. He said the opposite.
