Nice change from "Vertigo"

Yes, the movie did "balance out their talents" and end their year together on an up note so to speak.
Although realizing it's all subjective, I think Novak is one of the most underrated actresses of her time. I wouldn't at all describe her performance in "V" as "wooden" and imagine she delivered exactly what Hitchcock required of her. I know when the film wasn't initially well received that he tried to palm some of the blame onto his stars. I tend to believe that was more knee-jerk pride speaking and a lapse in his character.
Although Novak's role in "Kiss Me, Stupid" was rather small, it provides a good showcase for her comedic talents. While there's not a huge catalog of work to remember her by (perhaps by her own design or perhaps the result of studio backlash for her ignoring social prejudice of that era), her roles were varied enough that there's perhaps more range on display than even some of her more prolific contemporaries.
All-n-all, her body of work is impressive for someone who had no intentions of becoming an actress in the first place.
