I've no problem with Greystone per se; it's certainly got the right look -- although I really hope they don't go the route of just using a different section to represent the Old House. That was a terrible, transparent maneuver in the 91 series that really destroyed credibility in the setting.
Yes, well, following the WB Studios tour in 2002, Sheenasma and I are still trying to digest that the Duke boys' house and Boss Hogg's house from
The Dukes of Hazzard are, in fact, the front and back of the same house on the WB lot. But then you wouldn't know that just from watching the series.
TBH, I think we might even see a tower - that'd be very easy to add digitally. Thinking of it, there are lots of nifty digital fixes they could do... There's a walkway on the house that overlooks the vista of Los Angeles that they avoided showing in 1991 for obvious reasons - how amazing would that look with a cliff and the Atlantic dropped in?
Again, going back to info from the WB Studios tour, this is something that isn't even all that "new" in television shows. The home that was featured as the family residence in the opening sequence of the 80s series
Growing Pains was digitally altered. IIRC, the house on the WB lot doesn't have a garage, so it was added on for the opening.
Just, please, for the love of God, no crappy models in the opening of the new DS like they used in 1991. Every time I see that, I think of the bit about Camelot from
Monty Python and the Holy Grail. I also think about the opening of
Mister Rogers' Neighborhood.
