Storm King's Sandbox

What DM David said about Storm King's Thunder:

Here, the sandbox portion of Storm King’s Thunder fell flat. Once the adventure showed the menace of the giants, it left characters with no clear way to meet the threat. Instead, the characters could only run errands until they reached the adventure’s true start. The errands suffered from such weak hooks that DMs either needed to completely rework them or to face players dutifully following a course because the adventure expected it.

Sadly, true.
