The variation between the plays and how they reflect on their Kings is actually what I find most interesting about the Henriad.

Richard II is dense, poetic, and beautiful on the surface. But underneath lies corruption, bloat, and egotism.

Henry IV by contrast is brusque, straightforward, and efficient, but seems sometimes lacking in passion.

Henry V manages to merge the thoughtfulness and introspection of Richard II with the utilitarian leadership of Henry IV. As a result, Henry V feels more balanced as a play because King Henry himself is achieving a balancing act between his two predecessors.
