Likable
1. Ok Taec-yeon as Villain
2. Death Scenes of Hong Yoo-chan, Jang Han-seok & Choi Myung-hee
3. Park Joo-hyung as Vincenzo
4. Modern day relationship dynamics influenced by past instances & regret after losing loved one's (Hong Cha-Young relationship with her father & Vincenzo's resentment towards his mother)
5. Jang Han-seo character development. The only character that actually developed or improved with time according to me.

Dislikable
1. Entire Save Geumga Plaza Fiasco-Didn't like "over-the-top" sacrifices for Vincenzo. All tenants except monks & hacker were useless.
2. Over-Exaggeration of Consigliere & his Powers on other side Babel & power it holds.
3. Too many side-characters, divergence from main-plot, cassano family & filler comedy scenes.
4. Vincenzo's veiled past, Cha-Young's role from manipulative-smart lawyer being reduced to Vincezo's devotee. Reason behind Cha-Young's mother committing suicide & more shades of her character could be explored.
5. Jang Han-seok despite of being the mastermind relying too much on Choi Myung-hee for executing his plans & protecting himself.

Above Average-Neither too Good nor too Bad-Watchable after skipping filler scenes.
