Well, it was good - but not the humdinger of an opening episode that I thought we'd get.
There was some good stuff - but the big flaw for me was the endless whittering about 'the entail', inheritances and the law of the time: dry and confusing, and a barrier to engaging with the characters. Indeed, it felt odd to put the future of the estate at risk in the very first episode when we, as viewers, don't have anything invested in it. Add to that references to a number of characters we've never even seen and it all gets a bit difficult to get involved.
Thank goodness, therefore, for some well-drawn characters, even if some are a little familiar ...

However, greater focus and clarity to the plot would have helped massively. I can't help wondering if the 90-minute pilot was a hindrance rather than a help ...
As for the ratings, I'm sure it will have opened well but I'd wager some folk will have glazed over as the inheritance complexities rattled on. Coming off the back of The X Factor and with no competition on BBC One, I'd be surprised if it landed much less than 8 million ... however, if it's up against David Tennant in Single Father in a couple of weeks, it'll have to up its game if it wants to maintain that audience.
