first time watcher starting this series, with no spoilers please, what am i in for?

since the ALL the content from the election, its got me interested in this type of show & from what i have read, it seems to have been successful & has a big following, but does it hold up today do you think to a first-time watcher or was it the kinda show you had to experience in its heyday & can be rewatched today for nostalgia reasons or is it worth all the hype & i am going to be obsessed?

EDIT: 1st season binged in 2 n half days & you guys below commenting are all right!! I AM HOOKED!
