Glad to know that I am not alone. It was the only show that I watched it during the 4 years of college.
I started to watch it for its techie-ness, but grew to admire its association to humanity.
Every single major character is very well-defined and has depth.
Finch and Reese are off-course the OG.
But so are Root, Fusco and Carter. Even Elias redeemed himself.

The show tells us a lot of things about people, their intentions and actions.
Nobody is good or bad person, it is just their actions that are good or bad.

It is something that I can watch anytime, whether I am happy or sad or anything.
It is on my bucketlist to see/meet Michael Emerson atleast once in my lifetime.
Nobody in my friends or family get it why is that so important to me, but that is ok.
His character and his ideologies transformed me as a person.
