The pacing of this show is really bad. Whole episodes go by without anything really happening.
And when something does happen, often they're just going through the same problems over and over.
There are also 2 or 3 places in which the story and the behavior of the characters stopped making any sense. To the point near the end where a "surprise" felt so out of place that it felt insulting to the audience.
The neverending songs and flashbacks were mostly unnecessary.
Besides that, the acting of the main actors was good, as it usually is.
The quality of the sound recording and editing was often lacking, as it usually is.
