It almost seems all the creative studios in the country are intertwined with each other!Sparks did Talbot Street (though some from Sparks splintered and started Space Leisure hence a connection).
I really do think there are sometimes products which are cast off and designated to being supplements to other 'more important ones' which end up being a lot more original and unusual; I think the museums whilst small in scale seemed very interesting and well executed in presentation and style (from what I've seen of them at least). I'd be interested to know the alternative ideas had the budget been larger, but knowing the talents of those groups I can well believe it would have been very good.In all honesty, the other stuff like the Doll museum and model were because John Broome had just run out of budget, so wasn't really the best that the area could have gotten, which the people who built it would probably tell you too!
Doom and Sons looked absolutely fantastic, integrating a haunted house like attraction in to a town street area is very clever and really 'completed' the area IMO.
As for the area now, I just don't see what hope there is for it. It is tucked away I agree, but had it been expanded properly and perhaps been given a grand entrance to catch attention of visitors, I think it could of been one of the best sections of the whole park. It's just been steered in the wrong direction and you may as well say it's disused now.
