I found that it was let down by the use of incorrect dialogue, namely American terms that were not in use by the British public at that time. Rarely was the term "guy" used or the phrase "you are good to go" a dissapointing failure in not keeping it accurate. For the Era. A shameful let down by those responsible. In dramas of real life occurances accuracy is key. A very dissapointing failure in not keeping true to the time.
