Ongezellig has the best combo of main characters - the pynamic between energetic and silly Mymy, introverted and closeted Maya and overwhelmingly positive, yet with her dark side Coco is just unparalelled by any other cartoon I've ever seen. The humour is very decent and fairly special, thanks to the cartoon not being produced by a (former) youtube comedic channel Studio Massa. The storyline exploits questions of socialisation familial to all people, but even those, who don't experience problem with socialisation can enjoy either laughing at or undertanding the main charachter. The story also doen't have any randomly given magic(TM) or other escapist tropes, leaving it as a pure porteaition common enjoyable human experience.
This show is A MUST for everyone, I think only over-the-top smug people withought any humour may not enjoy it, otherise it is also quite short(one 25 minute episode), so there is literally no reason not to watch it. More people must know about this shining kino, so that it could get the nescessary funding and attention for continuation. It's not the last deel, its just the end of the pilot episode!
