Sadly I think this programme has now run its course.  When it first started I used to watch every one of the series and found it fascinating.  Now it has become mostly boring in the extreme and only occasionally do I watch a programme which I think might be interesting - and then have often been disappointed.  It's no wonder the programme makers have tried to introduce a different angle, but this approach doesn't seem to have pleased many of us, particularly the amateur genealogists, who like to see research to be properly detailed.
