Never played it,but I kinda get what you mean.
Well, you start with one character who doesn't learn spells. It is nice if you are just getting the whole concept... it is slow and boring otherwise.
I'll admit I got rather bored of IV myself, which is a shame because it looks like a title I would utterly adore if I could just brave the first few hours.
It picks up in the second chapter, which admittedly is only about an hour into the game if you know the beginning (which I do DQIV is a nostalgiac favorite of mine, I've played it about once a year since the early 90s)...
But honestly the only chapters I REALLY liked a whole lot were 3 and 5 (granted Chapter 5 is over half the game). Chapter 2 and 4 are good, but not great, Chapter 1 is boring as sin.
Chapter 6, added in the PSX remake in Japan, which is what the DS remake is based on is interesting as well.
