I do not want to compare it with any other series.
How I Met Your Mother (HIMYM) made me laugh during the toughest times of my life. It has friendship, it has love, it has family, it has sacrifices, it has pain, it has betrayals, it has emotions. Each character is special in it’s own way.
But the one thing I find incredibly awesome is the screenplay. They have referenced scenes in the upcoming seasons without any glitch.
*SPOILER*
The final episode of the final series shows how Ted meets Tracy - and that scene is soooooo beautiful and just perfect.
I have watched all the 9 seasons more than 5 times and I’m not bored in the slightest way possible. Do watch it :)
