I'm picking the next adventure path I'll be running for my group, and was wondering if there are any that people would absolutely avoid. I've heard bad things about Second Darkness, and had a not great time playing through Serpent's Skull, so I'm trying to make sure I don't sink any money into picking up books I won't end up finishing.
RotRL, Fire's Legacy, Mummy's Mask, Serpent's Skull, Skull & Shackles, Hell's Vengeance, and Kingmaker are all off the table for my group as different players have already played/run them... but hey, if you had a bad time with one of them, I'm not going to stop you from warning others away.
