i really enjoyed Train! it's a bit different to the investigative thrillers and time travel/alternate universe dramas that we generally see,, pitted against the leading series' in these genres, i do feel that Train falls short BUT i also think rather than a focus on impressive, sherlock-level sleuthing or back and forth between the worlds, this one was more about juxtaposition and the power of decisions.

they wanted to show how trivial decisions could potentially lead us on drastically different paths,, but also on the flip side, they entertained the concept that there are elements of fate in life,, and that although we choose route A or B, they could converge to give similar outcomes (i guess that's a bit of a consolation for those of us who experience mad fomo)
