Spontaneous | Rotten Tomatoes (1) Kristy Puchko Pajiba Brace yourself for an explosive and gory coming-of-age comedy, because Spontaneous is sensational, sick, and shouldn't be missed (again). Jan 5, 2021 Full Review Spontaneous | Rotten Tomatoes (2) Brad Newsome Sydney Morning Herald Estimable Australian Katherine Langford is fun and feisty as American schoolgirl Mara, and she has a great, tender chemistry with Charlie Plummer, who plays her sweet-natured boyfriend. Nov 11, 2020 Full Review Spontaneous | Rotten Tomatoes (3) Randy Myers San Jose Mercury News An absurdly funny, gripping and moving film that boasts one of the best screenplays of the year. Rated: 3.5/4 Oct 15, 2020 Full Review Spontaneous | Rotten Tomatoes (4) Jared Mobarak Hey, Have You Seen ...? That's how good Langford and Plummer are. Their snarky, sarcastic rapport makes light of everything so that they can smile through the horror. Rated: 8/10 Sep 29, 2023 Full Review Spontaneous | Rotten Tomatoes (5) Keith Garlington Keith & the Movies “Spontaneous” is the kind of movie that is sure to find an audience, but it’s skittish genre hopping could just as easily turn some people off. Rated: 2.5/5 Aug 17, 2022 Full Review Spontaneous | Rotten Tomatoes (6) James Croot Stuff.co.nz Langford delivers a fabulous performance as the audience’s guide Mara. At turns defiant, vulnerable, witty and warm, she gives Spontaneous its heart, as well as setting its sometimes anarchic tone. Rated: 4/5 May 6, 2022 Full Review Read all reviews

Jeremy A This is a great movie. I'm a little upset at the ending. 4* Rated 4/5 Stars • Rated 4 out of 5 stars 09/12/24 Full Review Ernest B Quick tip for writers of horror-comedies: the final 45 minutes should not be devastatingly sad. That's not what viewers are looking for. Otherwise excellent movie, ruined by third act tonal misadventure. Rated 2.5/5 Stars • Rated 2.5 out of 5 stars 06/09/24 Full Review Alyssa D The absolute worst movie I have ever seen. Seeing the rotten tomatoes score makes the website lose all credibility. Rated 0.5/5 Stars • Rated 0.5 out of 5 stars 04/19/24 Full Review Chester The relationship between sweethearts Mara and Dylan and how they react to their high school world falling apart around them forms the core of this dark comedy-horror film. Katherine Langford has 90% of the funny lines and the actress' timing and delivery are perfect, but many viewers may find her snippiness to be more annoying than endearing. Charlie Plummer is a dead ringer for the oldest brother from the pop group Hanson. Once a few of the students die, it actually becomes supenseful because you wonder who will be affected next. But I anticipated what would eventually happen and the change in this movie's tone that would occur. In real life, the vast majority of people would go insane knowing that, at any second, they might violently explode and it is not quite as simple as "que sera sera." If a scientific explanation as to the reason for the sudden deaths is given , I must have missed that part. Rated 3.5/5 Stars • Rated 3.5 out of 5 stars 03/31/24 Full Review Alessandro Ricci a Considering the medical profession we have totally hijacked and controlled by private interests through big pharma, the movie was hypocrite, pathetic and disgusting, as the "judgement" of critics, such as rotten tomatoes, where the indeed rotten critics scored 96 against an audience of 67, still ways too high if you ask me. American movies are indeed declining miserably, and rightly so given their pathetic and constant intrusions of political propaganda that destroy every artistic and creative aspect it might have had, just like the matrix, that had all the numbers to became the greatest shi-fi movie ever, settling instead as the greatest miss. Spontaneous is nothing like the matrix, but that's it's true gender: great miss. Rated 1/5 Stars • Rated 1 out of 5 stars 10/22/23 Full Review Andrei D Gets too dumb too quick Rated 2.5/5 Stars • Rated 2.5 out of 5 stars 10/01/23 Full Review Read all reviews
