Personally, I've always been a fan of Mr. Jacob's adventures (my personal favorite is the Red Hand of Doom).
The Brinewall Legacy brings adventurers yet again to the town of Sandpoint where they're hired by the local sheriff to deal with a problem involving goblins (yet again), those pesky little buggers! The plot becomes much more complicated as the PC's endeavors illuminate some interesting revelations about some of the townsfolk in Sandpoint.
I have a soft spot for 1st level adventures that give you a castle to explore, and JJ delivers with some new locations to discover in the Sandpoint Hinterlands.
The plot and the magic items are an interesting read and there is even illustrations for some of the key magic items. The villains are unique; making it a fun adventure to run for 1st levels.
The articles on the Tian Xia themed Oni are nicely done, making a superb addition for the first installment of the Jade Regent Adventure Path.
Some of the material is very similar to Paizo's very first adventure path, Rise of the Runelords (ROTR), and my only grief is that Paizo glosses over the town of Sandpoint in Jade Regent. The Rise of the Runelords map pack gives an excellent map of the town, but in order to get an idea of what and who is in the town you need to take a gander at Burnt Offerings (the first book in the ROTR) which gives a very good, colorful overview of Sandpoint. Obviously enterprising GMs with a crapload of time on their hands can adapt and create as necessary. But when time is in short supply, ROTR Burnt Offerings is what is needed to flesh out the starting locale of this adventure.
Sandpoint is unique in the fact that it's the only place that is a start off location for 2 Adventure Paths! So why not give the town its due with it's own mini source book? A source book that shows what the town was like before ROTR and after... Ah well, bygones.
After reading through the adventure, I noticed some of the ink came off and there are fingerprints on certain pages from the ink. So be careful when reading.
Regardless, the Brinewall Legacy is a great adventure for 1st level players and I heartily recommend GMs to purchase this product for a premade campaign to tantalize their players.
