The overvalue of some things

I'm exhausted of hear people groaning always because they say some things are overvalue and the hype is fake. They are too much subjective, don't blame on the taste of the others. For example I read comentaries saying this series is bad, first of all why are you watching a series that you don't like? Don't waste your time and the time of the others disturbing on something that you hate. On the second place you are annoying people who tries to watch it. This problem is present on all the series. For example when I see Narcos (the life-series of Pablo Escobar) some people loves it and others say it's horrible.
