First things first, this is not a 4 hour module. With all that is happening in ths module I'd suggest 5-6 hours to become full immersed.
This module is filled with some prett hilarious encounters and they can be pretty entertaining if run right. That said, with all the things going on in the town, it can be challenging for groups (especially those with low Int) to peice together the small strands of plot. For the first half of the module, it felt like random encounters to them.
The module reaches its climax outside of town in a pretty brutal fight. The fight has some tough opponents but there really isn't much of a chance to avoid the battle through social prowess.
The final encounter back in the city provides great opportunities for combat focused groups and social focused characters alike.
It is very clear that these mods have had a lot of thought and design put into them.
