yes thats obvious tho i was reffering to bolded in particular.I like Daleks
While it would be challenging to mesh these shows together it certainly can be done. Doctor Who has shown many times in the past that it can be every bit as adult as a show like BSG can. In the same vein BSG showed a lot of times it could easily be a juvenile soap opera. Sanctuary has also shown it can do all of the above.
The real challenge is mixing these shows in a manner that is natural and does not feel forced.
