just watched tgbm for the insane hype on social media and I have to say I wasn't really disappointed, but I don't think this is such a big title as the people say online... of course it's not a bad drama, but some flaws storywise and plot holes made me question such a high rating to this...

story: for me, this is the weakest part of the drama. I've seen so many people saying that this seemed so slow paced and so long, but in my opinion this drama should have at least 16 episodes to be a better watch. I believe that this drama would move a lot faster with more episodes because this way there would be more room for other happenings rather than just the recover of Kangho (I do know this is the point and the most important part of the drama, but I would never thought he would stay sick until episode 11/12!). this drama also didn't really worked as a drama + comedy show in my opinion... some issues here are way more important than they appear in the episodes, like the abusive household Kangho lived in the childhood! the way he was left with no apparent traumas or resentment seemed quite unrealistic to me. I hope I don't sound sadic(?) with this opinion ? don't get me wrong, but I think Kangho would be a character a lot deeper than he actually was in the drama if he dealed with healing... I know he lived the way he did mostly because of his mother influence, but I was hoping it was better showed in the show.
personally some characters actions are what bothered me the most, like the sudden change of thought Mijoo had about Kangho, or the sudden personality changes Youngsoon had, but beside this I really felt connected with the families, and almost all situations showed made me relate with mine :)

acting: even with the medium development of characters the cast here is fantastic! I really like Lee Dohyun works and think he is such a talented guy. I didn't know the Jin Youngsoon actress before, but now I really am looking forward to see more of her works!! also kudos for the little twins, they are really charismatic and cute :)

music: I really pay attention to the OST in dramas and they really play a very big role for me, but this drama has a lot more dialogues or scenes with instrumentals. the OST only appears few times and shortly, but beside this, I think the songs are great!

rewatch value: I don't usually rewatch shows... so I'm voting in this based if I did lol
even with some issues relating especially to Jin Youngsoon character, I think I would like to rewatch this drama because of the cozy vibes. maybe the flashback episodes, or the ones with family reunions, or the 13th one to have some fun!

overall, I think the good bad mother had a way bigger potential... they had such important themes to explore and I think they could have done a better job script wise :) even so, this is not a bad drama! maybe this is all about my personal expectations and how my personal approach would be related to some parts of the story, so feel free to chat in the comments if you want to!
