so i spent the last two weeks watching both of these dramas. and its crazy bc i went into taxi driver with high expectations because of its popularity and into beyond evil with no expectations because i just randomly stumbled upon it and watched 100% bc of shin hakyun, but i think beyond evil was a way better drama overall. i'll start with my general ratings:
Beyond Evil: 9/10
Taxi Driver: 7/10
taxi driver's biggest issue was plot holes and the lack of connecting previous plot points to character growth. I couldn't understand why they never focused on or had the prosecutor (hana) reflect on how she literally got 2 people killed and put people in danger by using them as "bait" on a case with no police back up more than once. this was something that beyond evil handled really well with personal guilt and lawful consequences juwon had to face for using someone as bait secretly which resulted in their death. also on the topic of consequences it was kinda meh that the rainbow transport team faced 0 consequences for the unlawful things they did. It felt like a complete 180 on kang hana's part after she spent the ENTIRE series hunting them down and talking down to them for unlawfully taking revenge, even after she used them to get back at her colleague's killer when she saw the prison they kept the abducted prisoners in. and then suddenly she just covers it all up, keeps working as a prosecutor, and joins them??? the end of beyond evil where even dongsik took responsibility and served time for his wrongdoing was way more satisfying.
taxi driver's nearly comical villains were also too over the top. i got that they were trying to show that some people will never be sorry for what they did and are just pure evil for no good reason, but literally every last villain became a caricature of that "pure evil" and then the concept of them being made to understand how they had hurt people wasn't even explored except for the one serial killer guy at the end? like what? the villains in beyond evil were far more believable because they had clear motivations for their actions and weren't just comic book villains with no semblance of humanity. this didn't make them sympathetic, but it made them human, which enhanced them as characters beyond the fodder the villains in taxi driver were.
overall i actually did like baek sungmi more as a final boss villain than han kihwan. but i appreciated the emotional strife han kihwan as the villain cause when there was rlly no emotional connation between sungmi and the other mcs of taxi driver.
feel free to share your own points on this. honestly i think taxi driver was a little over hyped and beyond evil a little underrated, but i generally enjoyed both dramas
