This is thus far my favorite module as a player and was the first module I ran as a DM. It offers a massive amount of flexibilty, for both RP and combat. It can be a bit daunting at first, but my players seemed to enjoy the bits of flair I added. While perfectly possible to run with a group of strangers, I can tell it would really shine if the DM is well versed in their PC's backstories. Heavily recommended whether as a quick session for beginners (though I would advise adjusting some of the combat) or as a longer session to really delve into the back stories of your table.
