The Series, and the plot at its core, are compelling, addictive even when firing on all cilinders.
However it feels like some possible plot directions have been left abandoned mid season for some reason or the other. As such the ending gives food for thought at first, but then slowly degrades in "but how did that unfold? Where did that need to lead to?" etc.
The other limiting factor, even though overall acting was great was the, at times, tonal differences. One moment you are sucked into a vague and ominous mystery while the next moment sees the show follow the antics of stoner teens calling each other dude while making puns. At those points it feels like there is a disconnect between the shows "Dark and Ominous" mystery thriller and "Teen Comedy".
Still a good watch, but not as highly praised as some others in its genre.
