I think that the title of this review describes fairly well this part of the campaign.
The first part consists in a long trip scattered with encounters that have nothing to do each with other.
The second part is a little adventure with some investigation. After that comes another not so long trip through the North Pole with more encounters with no connection with the story (nor each with other). The part ends with an absurd tower where the point is throwing d20s decently to travel from one floor to another. There is an unavoidable combat in each floor. Very interesting...
The third and last part I have not played yet, but it seems to be somewhat better...
By the way. I had to skip the whole first part because in the beginning I decided not to use caravan rules (rules that have the power of converting a tactical combat with spells, feats and careful movements into a boring sequence of dice results).
Probably the worst thing that Paizo has published so far.
