It's strange, I rarely write reviews on dramas I've dropped but Que Sera Sera is different.
It has one of the most classic and fascinating plots, and it's worth watching in the first half.
The 2nd half is where the problem begins, it turns into a disdainful melodrama which is pathetic to watch.

The writing is top-notch although it fades away in the 2nd half.
All 4 characters have been given equal screenplay time which is fascinating to even think of.
The tone is solemn,
What Irked me most is the fact that it starts with a fixated plot but the change of characterization into disdain is pathetic.
It ruined the drama for me enough to drop it.
There could've been a different timeline for this drama to achieve much more success , sadly it focused on the pity part .

~ Also this is the first time in a drama where the 2nd FML had complete domination over FML simply due to her role.
She was better at acting, better dialogues.
FML was shadowed by the 2nd FML.

~ Coming to the soundtracks, My goodness where do I start, the sound director of this drama deserves an award.
Such great soundtracks, you could literally feel the jazz and pop theme around the mid-2000s.

Overall this drama is a great package, the ending is predictable still worth watching in the 1st half.

PS: Some people who're overly sensitive might feel the intensity of this drama, but that's how people are.
Remember this isn't a fancy drama, it's a toned drama based on realism at times, it's not the best out there but it's fun to watch.
