Parade’s End is not Downton Abbey. That doesn’t make it better or worse than Downton. It just makes it different. For starters, it’s a five- part miniseries, without the unashamed soapiness or multiple characters Downton fans so love. Front and centre here is the love- triangle of the reserved civil servant, Christopher Tietjens ( Benedict Cumberbatch), his adulterous wife, Sylvia ( Rebecca Hall) and Valentine ( played by Aussie actress Adelaide Clemens), his meek devoted mistress. Tonight’s opener is sumptuously shot, occasionally straying into bodice- ripping and seriously overwrought territory.
