I've only watched the first one, but I would highly recommend it! Sure, it has a big number of episodes, but they are only about 20 minutes per episode. so it is not that long. It is so funny that my stomach hurt from laughing. Although it's funny, there are also some serious topics and scenes, so it's not only comedy but also some drama (though the comedy is a lot more). The characters are really interesting. There are quite a few characters, but they are all connected in some way and it doesn't really take long to get familiar with them. They can be quite stereotypical, but I thinkt that this adds greatly to the comedy.
Have fun watching :)
