I thoroughly enjoyed it, as you say the battle sequence of Agincourt ....The King on Netflix.
Owes nothing to Shakespeare or history but is very watchable indeed.
Despite looking like a medieval Marc Almond the protagonist does a good job of things but the standout role belonged to Joel Egerton as Falstaff.
That guy turns up in some diverse roles but nails it each time.
The brutal melee in the mud at Agincourt was superbly filmed and you couldn't help a grin of satisfaction when the Dauphin met his end at the hands of the common soldiery as he slipped about in the mud.
Mud Mud and more mud if you missed it!
