I must be honest, I was gutted when the original series was cancelled, ITV seem to have a nack at cancelling shows when they're at their peak, or simply showing signs of developing into something good, The Halcyon and Home Fires to name a few. It was therefore hugely welcome news to learn that Omnifilm had decided to bring the show back from extinction, the challenge was always going to be whether or not they could capture the quality and feel of the original. For the most part the answer is yes, Julie Graham and Rachel Stirling survive from the original run, and provide enough presence to make it feel like Bletchley. It's well produced, the stories are good (maybe not Madhouse so much,) and it deals with some very serious issues, notably sexism and racism.
It's a good series, I think it's fair to say it doesn't quite have the quality of the original runs, but I'm glad to see it back, and I enjoyed it. I look forward to the next four episodes. 7/10
