It's not a matter of faith, it's a matter of evidence. If it doesn't work, it doesn't work. But we've seen no character designs, no plot ideas, NOTHING of substance. I'm willing to reserve judgment until we have something to really base an opinion on.
I'm not a huge King's Quest fan, though I've played I-VII (and visited Serenia in Roberta's earlier "The Wizard and the Princess"), so I'm just looking for something to make me excited about returning to that universe.
