The series is pleasant and, conceptually, is inspired by Lost (the presence of one of its protagonists does not seem to be causal).

The problem, however, lies precisely here: the first season ends with all the questions still open and there are so many irons in the fire that it is feared that it will not be closed quickly or well (as happened precisely with Lost, which was phenomenal in the first three seasons only to struggle in the subsequent ones, also thanks to the US screenwriters' strike).

I'm starting to prefer miniseries...
