If you want to enjoy the legal aspect without it being too serious and emotional. Light hearted and both fight for the rights of the powerless.
If you love being depressed and do not mind a few light moments here and there.
If you love small town culture. Filmed in the same city. WTCB is much more than a murder plot and there are times when it's barely even there. The overall vibes are the same.
If you want to be physically uncomfortable and terrified. There are no jumpscares or disturbing imagery.
Penthouse is Sky Castle but on steroids. Do not watch if you get easily annoyed because high blood pressure is guaranteed.
