If it's a few weeks just to watch Ozark, then fine. Just be careful to abandon your account and never renew if you wanna watch just one show.
I don't have insider data, but I guess many people only watch Netflix merely because they are paying for it. It's this psychological mechanism that has people watching just because they pay for a sub.
Once you research the best shows to watch, you can watch them all in succession, then destroy your account and carry on with other duties.
You have that choice.
