The real start of the story?

I started the series just after I finished reading the adventures of Fitz in Royal Assassin (very big "slap" for me) and past the first 2 volumes rather disappointed I stayed on my hunger ...
I found bland characters without depth, the style might be simpler, flatter the plot ...
It must be noted that this third volume will wake me!
The characters begin to unfold, the story thickens etc ...

In short that happiness was only one desire: to know the rest! The real beginning of the cycle for me.
