One thing I wish Marnie hadn't done...(Spoilers)
I didn't like the part where Marnie smashed the vase that Will and Joanna had gotten as a wedding gift at their rehearsal dinner. Then, after that, Marnie stepped over the glass and said to Joanna something like, "I've always wondered what it would feel like to finally stand up to you, but now I realize it's not worth it." In light of that particular line, this scene probably would have worked a lot better if, when Joanna begged her not to smash it, Marnie just kind of shook her head, put it back down on the table, and gone into her little speech about Joanna not being worth it.
Anyone else agree/disagree? Would you have broken the vase if it were you?
