In part two of "May the Farce be with You," we're looking at 2015's attempt to reboot a beloved comedy franchise...but this time with a new leading man, new attitude, and without a signature part of the original title. What makes for an effective "legacy sequel?" Is Ed Helms as strong a lead as Chevy Chase? And just how mean-spirited is too mean-spirited, when it comes to comedy? All this and more is discussed, as we look at "NOT National Lampoon's" Vacation.
