Her performance has been widely acclaimed: Variety praised her "excellent supporting turn," The Playlist highlighted her portrayal as "one of the finest seen from any actor on any screen," and Screen Rant called it "essentially flawless... eloquence and vulnerability." The second season has become the highest-rated live-action Star Wars series on Rotten Tomatoes to date. The first season was nominated for Outstanding Drama Series at the 2024 Emmy Awards, won a Peabody Award for Entertainment, and Genevieve was nominated for Supporting Actress - Drama at the 2023 IFTA Awards.

The film opened at the top of the Australian box office on New Year's Day and achieved the fifth-highest opening day for a local film in history. Released by IFC Films in the US, The Dry (2020) garnered similar acclaim and was announced as runner-up for Best Narrative Feature at the San Francisco International Film Festival. Her other notable film appearances include Tolkien (2019), the biopic of the iconic author J.R.R. Tolkien. The film explored Tolkien's formative years against the brutal backdrop of the First World War. Additionally, Genevieve appeared in the acclaimed films The Legend of Tarzan (2016) and The Young Victoria (2009).

She reprised the role on Broadway following the production's record-breaking, sold-out run. Directed by Sam Mendes, the play won three Olivier Awards, Evening Standard Awards, and a UK Critics' Circle Award for Best New Play. The New York Times called the production 'fiercely gripping,' and The Hollywood Reporter praised Genevieve's performance, noting her 'gorgeous speech,' which 'spills out full of conflicting impulses of hurt and compassion.'
