The Big Bang Theory will be a series like Friends, which remains in time despite being a few years old.
What I liked most about the series were not only the situations the characters went through in each episode, but the evolution of the characters during the 10 seasons of the show, the most striking for me, the evolution of Sheldon who in his final speech after winning the Nobel Prize, recognizes the family that always accompanied him in these 10 years.
Undoubtedly it is a series that I would watch one and a thousand times more, it does not go out of fashion, it is good that you have brought it to this community and we can remember it.
