Surprisingly entertaining this show manages to be family friendly instead of simply kid friendly.
It is bursting with personality. To strike a more suitable comedic tone it seems that a few characters were inspired by their puppet counterparts in the Robot chicken shorts. The emperor especially is just a treat to watch him and his antics.
The main characters are also quite well written. The Freemakers do feel like a real family. it is quite heartwarming to see them work together.
Furthermore the setting makes perfect use of the lego star wars setting by merging the master builder concept from the lego movie with the concept of the force. The result is quite unlike everything else in the star wars franchise and a breath of fresh air. using the force to build instead of throwing stuff around allows for a lot more creativity on the part of the writers.
Finally, while a few people might lament the status of the show as non canon to the broader Disney Star wars franchise i must say that this works to the show's advantage. It has far more liberty in its storytelling by being in its own canon.
