This review is for Giantslayer
I ran "Giantslayer" as introductory adventure that will influence and kick off both Lost Mines of Phandelver and Storm King's Thunder, and I have to say, that as a table we loved this adventure for its story, its NPCs, and the learning opportunity it presented our one brand-new player.
The satyrs taught them that murder is a last recourse, the mephits that there is always a risk for reward, the NPCs that there are lovable albeit with flaws in a living world, and the giant taught them that comradely, planning, goodly intentions, and elbow grease can go a long way against the least reasonable and mightiest of foes.
I highly recommend this adventure for any party (level 1–3). To those DMs who run this, might I recommend the following: 1) Keep a mental image of an abandoned Scorton in case your PCs decide to head there and investigate, 2) Write a short script that gives Pello, Grigor, and Tastra some personality. I played Pello and had two volunteers from the table read the other two. This was the true highlight of our session, 3) You can always ramp up Yegor's hp if you have a large or capable party. I gave him +40, and they still made short work with zero casualties, 4) Yegor is easily linked to Grudd Haug in Storm King's Thunder. That area is too difficult for them now, but if you make it clear that Yegor came from the south, they'll connect the dots later on, 5) Link the giant that Jahan slew with a giant, tomb, or monument that your PCs can discover somewhere down the line; and 6) pre-roll some random goodies from the "giant's bag" table in the SKT hardcover. My party found a barrel full of bees and honey. Risk-to-reward, my friends!
