Start-Up is one of the most horrific dramas that I unfortunately watched.
One might go by the catchy title and think this would be a good drama but it isn't.
They decided to touch the enshrined part: TECHNOLOGY
which by any means should've been researched about properly, but what we get is half-baked tech forcibly engaged in a terrible Melodrama exhausted by a woman's fantasy.
Everything that was done and each step taken was a huge JOKE in Tech counterpart.

YEP, THIS DRAMA IS A TYPICAL WOMAN'S FANTASY WRITTEN IN THE MOST HORRENDOUS WAY
2 GUY'S LOVING HER.
A FIRST LOVE.
HER BEING A TECH LEADER AND CEO.
WANTING TO SUCCEED
FAMILY SACRIFICE.
BLAH BLAH!
EVEN AFTER ALL THIS, SHE SUFFERS!
Oh Gosh !

Any CS person or even a sane person who knows a bit about technology will absolutely find this drama a complete disaster.

Plus, there was Zero chemistry.
The acting was a disaster.
BAE SUZY CAN'T EVEN ACT!
They messed up it to the whole by casting her.
This has to be the worst show produced by Netflix so far.

PS: This drama tried to be something like MISAENG but ended up being total BullSH*T !!
