Medieval realistic role playing
"Realistic" is used very favorably in this case... I get what you mean: Henry's story feels plausible enough to suck you in and I don't mean this as a critique. But it is in no way realistic: Henry starts as a smiths son and is pretty useless at everything but he becomes a proficient fighter in the story and as far as I remember pretty influential. This is extremely unrealistic for his timeline because social mobility in the late middle ages was very much on existent.
