With the HYW being an almost lifelong obsession; I'm reserving judgement.
It's definitely based on Henry IV and Henry V by the Bard. I do hope that it has some twists and turns that are not already anticipated by Shakespeare.
From the brief bit's I've seen on the trailer they appear to have got the look of the thing more or less correct but I might live to regret making that observation!:)
I'm looking forward to seeing it, it hits Netflix UK on November 27, 2019.
Kind Regards
