Unforgotten Night is a disappointing Thai BL drama that fails to deliver on its premise. Despite the attractive leads, the series suffers from lackluster performances, awkward chemistry, and an underwhelming storyline. The BDSM elements are poorly executed and fail to create the desired intensity. The mafia setting is also underdeveloped, falling far short of the engaging portrayals seen in dramas like KinnPorsche.

While the series has a few redeeming moments, such as the confrontation scene between Cherry and Kim, these are overshadowed by the overall weaknesses. The supporting characters, particularly Cherry, are underutilized despite their potential. The inclusion of scenes in the trailer that are not in the final product adds to the confusion and disappointment.

Ultimately, Unforgotten Night is a FORGETTABLE experience that fails to leave a lasting impression. While the leads may have future projects worth watching, this series is unlikely to be remembered fondly.
