Let's see -

Like:
Yin and War are still good together. Though it is War that emotes it better.
Depiction of true poverty. Really brought to life the effects of debt and poor choices. The sweaty faces (may not have been part of the script), cramped tumbled rooms and scrappy clothes made the setting believable.
Grandma bringing the comedy and sound counseling.
Rose accepting the refusal with a little class and not hanging on for scraps.
Bad happens to everyone. How it is dealt with is on you. Same event but different choices between Nang and Boss.
Aran's downward slide into poverty was covered.
Aran building Tattoo's ego when he needed it most.
Joke crying. Again, I repeat, Joke crying.
Hope reminding Jack that he had to do some dark shit for Boss, also.
When Joke saved Jack from Boss without telling him that he saved him.
Joke raising his hand to touch Jack's face but stops midway as Rose interrupts. Jack sneaking one last look at Joke as he goes through the doorway.

Hate:
Everything else.
Script felt like I was watching an ant farm. All over the
place with a ridiculous series of events and asinine characters. Four Horsemen? Chutes and Ladders? Collars that could detonante? A ring that turned Boss into gollum instantaneously?
Jack going back to Boss immediately.
Over the top acting.
Joke getting caught the majority of the show. A master thief he was not.
No explaination as to what was Joke's learning difficulty but he is a teacher for the impoverished children. How? Make it make sense.
Humor that was not humorous.
Joke looking clownish in some of his disguises.
Joke spent 5 years in jail and still got beat. What did he learn? How to pick the ugliest comical tattoos? The boy went in jail looking wealthy and came out like he was from the ghetto all his life.
Jack helped the entire neighborhood but grandma was still in poverty.
Boss' laugh.
The struggle of who would top? Not necessary to the script.
There was no real charm to their relationship and seemed lacklustre at the end.

There is more but I'll stop here. The entire production team can go back to school to learn how to create a series within budget with a coherent plot and engaging characters. Jack and Joker was a sweaty mess from beginning to end with too many characters and very little plot to tell a cohesive story. While actors can look for roles to show their versatility, Yin and War can do better. The beginning was good. The ending was not.

Rewatch: Only if grandma is hurling a plate of chive dumplings at me.
