We need more period pieces these days.

If you have a problem with historical inaccuracy, just straight out avoid this film. Having said that, The King is a valid fictitious portrait of actual historic events and lives such as that of Henry V, appreciably portrayed by Timothée Chalamet, in a correct performance that doesn't strike at first but slowly begins to entice. Historical subject matter is dealt with care and attention to details, minus some historical facts which history buffs are not even done complaining about.
When I was watching the film, it felt slow and tedious in some moments, unable to grab my attention to its full extent. The pacing can be quite damaging to this film, although it's easy to confuse slow pacing with slow tension-building moments, which are done purposefully to generate impact at certain points in the film.
Perhaps you could compare this film with Kenneth Brannagh's 1989 film Henry V, which was adapted from the Shakespeare play, and its dialogue is million miles away from the one in The King, but both portray king Henry V in different manners, in different tones even, with both title performances being up to par. Robert Pattinson's performance is excellent, if there is someone who shines in a role, it is him, without a doubt, and his French accent is delightful.
Whether you are into English history or are a fan of Shakespeare's Henry V, you probably won't enjoy much of The King, but you could certainly try if you want to. Otherwise, I think this is a quite enjoyable film, one of Netflix's best productions for sure.
