They Wasted a Perfectly Good Plot: Meg and Zack's wedding. Before Meg's Boyfriend shifted to episodic adventures, it spent time on their relationship and the time they spend together, up to and including taking care of Meg during her pregnancy. With how well these two have been getting along and the things they went through, one would think Malcolm Fox would have added a wedding chapter to the schedule. Instead, their wedding was glossed over with Zack saying "Oh, right. We got married yesterday in Vegas. I keep forgetting." This is an odd and unintentionally jerk-ish thing to hear from basically Meg's Mr. Perfect—and at their child's birth, no less.
