If you enjoyed the film, Master and Commander, or read the books of Patrick O'brian and are looking for more, then Hornblower is perfect for you. More high seas adventure and swashbuckling than you can throw a stick at. Considering the lack of a hollywood budget and the fact they were made for TV, this series is just amazing. The navy based equivalent to Sharpe, I would strongly recommend this to anyone who enjoys a bit of action and adventure.
Would also say to shop around, not sure how long it will last for, but have just found it online at HMV for £17.99 in the sale, now that makes it even better.
