So you are of the opinion that Mines of Phandelver has an exciting hook and Phandalin is an exciting town? Because that what we were discussing and not how beloved the adventure was. I also liked to run it btw. I like the structure of the adventure, I like the dungeons and battles. I just find the setting too bland for an introduction into the genre of fantasy. The backdrop is not fitting and I can really don't understand how people seem to disagree, it really doesn't get into my head.
"Your fantastical is potentially my outrageous". I am sorry, if you find fantastic elements in a fantasy game outrageous, why are you playing dungeons and dragons? I am not talking about a city floating upside down over a volcano with a population of wherewolf pixie hybrids. Just give me one or two special little things in the town that makes the town special. Not even a low level hedge mage lives here. Every random generator produces more interesting cities than Phandalin. In theory Phandalin even has the potential! The new frontier town is built on the ruins of the hundreds of years old town that was much bigger but destroyed by orcs according to the description in the adventure. But we can see nothing of that except some cobblestones on the map. Let the players explore some ruins, find out lore about the old Phandalin, meet ghosts of the ones massacred by the orcs. Also from a narrative perspective Phandalin is so empty. The factions are represented in the town but nothing happens of it, except maybe a bit with Thalia, but you need to really push it by yourself as a DM.
Dragons of Stormwreck Isle is much more interesting as a starting adventure for these reasons IMO.
