"War at Sea: Dreadnoughts at Scapa Flow".

I thoroughly enjoyed this last night - some great shots. However, what most impressed me was the use of original footage and the attention to detail. They talk about HMS Lion, we see HMS Lion, for example - someone did their research!
It's a bit edited (time available?) when it comes to the detail of the fleet actions, but if this is what the BBC can do with regard to WW1 naval history then I am ready to be impressed in May next year.
