Collider highlights Korean dramas that have maintained strong quality despite running for five seasons or fewer, an unusual achievement in a format usually built around self-contained 16-to-20-episode stories. It argues that these series avoid the decline often associated with later seasons, whether ending after a single run or developing into a longer franchise.

– Weak Hero: A school-action drama about academically gifted but physically slight student Yeon Si-eun, who counters bullying through strategy. Its acclaimed 2022 first season was followed by a 2025 second season, which topped Netflix’s non-English chart in 32 countries; some fans preferred the tighter original season.
– Taxi Driver: Lee Je-hoon plays a former special-forces officer working with a vigilante taxi group to seek justice for victims failed by the legal system. Adapted from The Deluxe Taxi webtoon, it grew in popularity across its first two seasons, with a third season approved shortly after season two concluded.
