i can see what you are trying to tell. i have not seen nirvana in fire. but heard lot of praises. i am not aware of maybe "awesomeness" as you say. but NIF being historical and also lengthier drama, people may not be ready to go for it. all those who like signal are genuinely giving their heartfelt rating or appreciation. as nastou19 says signal did not start as popular drama, you know something like descendants of the sun. it was aired on cable channel. its initially ratings were also not that high. signal may not be best crime thriller, but it strikes chord in its own way. it slowly drawn attention not just for international viewers like us, but also for koreans themselves.
i agree to your remark on romance aspect, it may not be upto everyones taste. but signals romance is very subtle, it doesnot affect story line much. it also goes smooth, blends with story line. without much interruption. and i like that.
having said that, NIF is already on my PTW list. i am trying to make ample amount of time, to start it. if i see awesomeness i will definetly appreciate it. its not like to glorify signal more than NIF by eulogising it. but this post of yours is a good thing. all those who are unaware of NIF, may give it a try. at the end, people may become open to wider tastes
