The kingdom stuff has two major problems:
- Tying the player's time up when you have to skill up an advisor
- Not enough impact upon the game itself.
For starters — rather than turning it down to easy, I'd suggest getting the kingdom management mod that lets you disable #1.
#2 is, however, a flaw of the game itself. There are some repercussions(e.g., entering a trade deal with one of the nations — can't remember which — accidentally gets your kingdom hooked on drugs), there should have been a lot more.
