Signal (2016)

same feeling... guess while watching signal the writer of tunnel thought- wouldn't it be better if the cop came to the future himself rather than just talking through a walkie talkie. almost similar dramas

While both Kdramas revolve around injustice and crime, the female leads are strong, unique and independend. Additionally, the male leads in both of them are rather imperfect and have a healthy amount of character development during the series. Both remain exciting until the last second.

Almost the same storyline just that one communicates using an old cell while the other using a walkie talkie.

fishy, full of mystery, murdering. The way the team work hard to solve case. everything is made as a puzzle which is really hard to be predicted. if you like something as thrilling as signal, then this drama must be your first choice. Veteran actor play in here, with great acting.

Solving crime through time, the only exception is in "To Get Unstuck in Time" the son is contacting his father 20 years in the past.

Both are crime dramas with past settings involving serial killers and police officers trying to catch them.

The mysteries in both plot storys, it makes you question so many things wrong with our society today. Corruption, why we murder.. The plots are 'somewhat' similar in terms of the genre and a bit of the character buildup but totally different in someway. Both dramas are a must watch, and will definitely not fail to please or surprise you.

Have to really recommend this as its very similar plot, just diff with mobile phone vs walkie talkie.... Equally exiting n suspense...

They both contain people who communicate with people from the past. They also try to save people who they love with this method.

....................Both are crime, thriller dramas that have plenty of plot twists ...........................

Watch it if you love dramas about time travel and particularly stopping crimes from happening. Both are amazing and will leave you craving for more. Smart male leads.

Homicidal events of the past collide with the present. The actions of the ML in the current future could alter the past and, thus, alter his own destiny.

Both a extremely well written and directed tvN shows that both aired in 2016. Both focus on cases that seem irrelevant at first but tie up really well by the end. Though I would personally favor Signal for its unique time travel aspect and how it moves on from case to case almost effortlessly, Pied Piper does not disappoint in the least. The thrill both shows give, specially in the latter half is wonderful. If you liked one, you'll love the other.

Two people, one in the past and one in the future, connect to solve their problems...................

Signal popped into mind a few times watching Missing. Similarities to me were -Both ML’s got pushed into their abilities unintentionally -Both MLs have similar personalities…righteous, strong but gets emotional for the victims -ML partnered up with another Older ML -ML with older ML solve murders that were often years unsolved Both these dramas have excellent plots & cast.
