Both are murder investigations. It is also uncanny to watch Frederick Lee in this, and Christopher Lee in Danger Zone...
Both are similar genres: fantasy + comedy + life philosophy (or slice-of-life) + romance. And they are from the same production company ;)
Both are realistic slice-of-life dramas, focusing on sensitive topics. While Remembrance is about suicide and young adults working lives; The World Between Us is about a mass murderer and the effects on his family and the victims' families.
Both are shot few years back but only released recently. Same rich people setting, schemes and plotting at business and similar rom-com vibes (although Tears in Heaven has more cliches)
Both have alien species on earth, and trying to live like humans. Similar modern setting with flashbacks to past era times.
Both are murder detective drama (Dream Detective has several cases, while Horizon Tower is only 1 case), have same dark theme and shine a light on social prejudices and injustice. With very strong acting cast and well-paced plot **thumbs up**
Both are historical dynasty dramas that focus on politics. And I feel TROP might have been much better at the hands of director Patrick Yau. SOTK is a stunning, gorgeous drama shot like a movie (especially at the first episode). It also has better, more realistic dialogues and plot suiting the dynasty times.... The actress to pay attention in SOTK is Regina Wan! She put up such a fine performance *thumbs up*
