Virtues:
-The gorgeous cinematography.
-Jespipat Tilapornputt and Asavapatr Ponpiboon's performances are really good.
-The 4 minutes concept and the near death experiences theme.
-The mix between the mistakes of the past Great wished could fix, the raw and messy reality the characters lived and the things that never happened to Tyme but wished would have happen, all of this three timelines told with the central context of being on the verge of dying.

Flaws:
-Some events happen out of the blue, with a poorly elaborated build up, so the development and the characters' relationships, actions and reactions lack credibility at certain moments of the story, special mention to episode 6.
-Some scenes, like the one when Tonkla has the camera right in front of his face to show he's succumbing to his dark side born from his traumas, the one when Great and his father "argue" about the video or the one where Tyme comfronts Great's father are badly directed and filmed, and therefore, acted.
-Sammon repeats things she'd already used in previous plots without giving these resources proper personality.
-Some sequences feel like being watching a TV spot, a beautiful advertisement or a promotional ad for the actors. Including all that in a series is perfectly fine and common, but you must know how to integrate those promotional things in the general story in a proper manner. Unfortunately, here and in Thai series in general, they just throw the promotional things to one's face, which took me out of the story more than once.

To sum up, 4 MInutes is an interesting and enternaining midnight series that is not perfectly written, but is still worth watching if you're looking for a decent BL to watch.
