You've every right to complain and I agree that something has been lost. I've watched DW since the first Doctor (I was 6) and I watch it still, but I don't expect nor want the stories to be for me as an adult. In the next 2 specials, I can't think what story they'll run underneath the adult stuff that the kids will understand, but it'll have to be a good one or it'll be a huge betrayal of the show (but I'm not holding my breath).
