Greg Wheeler of The Review Geek wrote: "A boy and a girl from polar opposite backgrounds come together and find love. It’s one of the oldest rom-com tropes in the book and yet every year there’s a whole wave of titles that rehash this idea and put a slightly different spin on it... Step forward German Netflix film Isi & Ossi that takes this cliched idea, intertwines two big dreams together to produce an indifferent, painting by numbers picture that does little to stand out from so many others out there." Wheeler, however, praised the performances of Vicari and Mojen and their natural chemistry.
