I am trying to think of the series as a whole thing and judge it based on all the episodes. But I just can't, the ending killed every little good thing about it (and there weren't that many, to begin with). The cast was good. I think they fulfilled the roles they were given, but I admit it wasn't anything exceptional. Since 5e whole plot is travelling into the future, you are prepared from the beginning that there is a big possibility, that it won't end well. You have a mother who died after her son went missing so of course he has to go back. But the fact that many many years later he still approaches a teenage guy like that really didn't sit well with me. He should have cherished him as a beautiful memory and even if they met so many years later he should just step back and watch him from afar. I admit the ending was kinda making me a little Ill. Maybe it's thanks to the fact I am now over 30 but relationship where there is a big age gap and one of the couple is still a kid, it just doesn't sit a well with me.
