Both are dark and gritty dramas with a similar feel to them. They both have unconventional protagonists who are criminals/involved in the underground criminal world and deal with organized crime, are filled with action, and contain interesting plot twists throughout the series.
Both feature sexy psychopaths. Bad Guys has Park Hae Jin. I Remember You has Park Bo Gum. While there is a romance subplot in IRY, in my opinion, there was zero chemistry. The real draw for both dramas is the bromance, the team comraderie in BG is great. And, the real chemistry in IRY is between Seo In Guk and Park Bo Gum. Highly recommend both.
As fellow OCN dramas, these shows share a considerable amount of similarities: (1) the beloved dark, gritty OCN ambiance, (2) tortured male leads with cryptic pasts, (3) an overarching mystery that is slowly unraveled within the story line composed of numerous smaller cases, (4) quick, brutal violence that is generally mob vs 1, (5) growth of the camaraderie between unlikely partners, and (6) I'm sure many other similarities that will be revealed as the season continues!
A less-than-human-becoming-human journey.
One of main characters in both movie and drama is a very similar dark (scary, but also kinda... cute?) psycho with some deep issues and history of psychological (mis)treatment. Both stories show us a lot of violence and you can't really figure out the psycho character till the very end.
Difference between these two is mostly that Bad Guys is a drama and not a movie (so not as short and has more story parts intertwined) and has other significant and complicated characters aside from the psycho.
