Also read it but haven’t run/played it. A lot of the earlier episodes feel thematically similar: you need X so you can proceed on your main mission, but before you can have X the person who has it now needs you to do Y.
The latter half is very sandboxy. I’m not really good at running sandboxes as a DM, so that was a little bit of a turnoff to me but others may love it.
A lot of the adventure feels grimdark. Players are often required to make morally grey decisions at best, and sometimes the best decision to accomplish their goals would be an evil one.
In the end, the party doesn’t even end the large evil, they just prevent a possibly worse evil from happening. This, combined with the grimdark tone, could be a major turnoff to a lot of players who prefer to feel more heroic.
