Taking a cue from Melf I thought this might prove to be an interesting topic. However, this is not meant to attack or besmirch the writers. Keep it civil- and let see if there were other bad experiences in modules. I'll start... I was the DM for the four module series Dragonlance DL1-DL4. We decided to play in this realm as a change of pace from our usual GreyHawk setting. The players hated this modules series because it was a forced series of events that they had no control over. They were lead (or forced captured) through almost the entire series. Free will they had none- and eventually we quit playing the series I think DL3. Initially I thought it was me being a bad DM, but to a person everyone stated the series sucked- and we went on and had many successful campaigns through the World of Greyhawk!
