The IDEA of Dragon Heist is apparently pretty cool. And in the hands of a skilled DM who can urge the party along the right path, and figure out how to troubleshoot on the fly, it's probably a blast.
The elevator pitch is a good one - "Ocean's Eleven in D&D? Sign me up!" Unfortunately it comes off as pretty half-baked and while I acknowledge there's always some on-the-fly improv a DM needs to do, it is way more than should be expected in a fifty dollar product.
