If There had been an option to write separate reviews for the first and second season, the reviews would have been completely different.

Sure, season 1 had its problems, but still it had many strengths. Some episodes were really powerful, while others failed in realism. Regardless of the flaws I could not stop watching the first season.

Now, on the other hand, I have to force myself to keep watching the second season, and to be honest I doubt I'll finish it. It is as if completely different people are making the second season, people who didn't really watch, or at least did not understand what season 1 was about.

For example, one of the protagonists (the living one) suffers from an immense frustration, brilliantly portrayed, I might add, over the fact that he has so many questions to ask the dead girl, and so much to say, but he can't because... well, she's dead. And now in season 2 she's back in the shape of some kind of mental ghost with enough agency to act as her living self. More, in fact, like a ghost than a memory. And all of a sudden, one of the more gripping things about the first season is gone. Completely. Like most other things that made the first season powerful.

That said, watch the first season and leave it at that.
