According to film observer Shandy Gasella, "this remake is not as sitcom as the original film by Hwang Dong-Hyuk. The tone of the film is soft and happier, I like the grading. There are many additions of scenes of laughter, making this movie feel 'the same but different'." However, this film does not improvise much from the original film, and even though Fatma admires Mieke Wijaya, young Fatma's makeup is unlike Wijaya's.^[3] According to Jodhi Yudono from Kompas, Sweet 20 managed to be a family drama film as well as romantic comedy that is thick with the colours of Indonesia, both in settings, such as putting the atmosphere of Lebaran and conflict between children- and parents-in-law, and jokes throughout the film. This film also mixes senior film stars with recent actors, creating a nostalgic nuance.^[13]
