Don't share your account
On that note: altruism is all well and good, but if you're going to give your password out, make sure you tell your friends (and your friends of friends, and your relatives, and your friend's relatives, and your friend's relative's hairdresser, etc.) to create their own profiles. Remember, Netflix is smart as hell and everything you watch goes into its recommendation algorithm, so don't let some plebe with bad taste fill your feed with bad mid-aughts procedurals. (Seriously, whoever keeps watching House M.D. on my account, please stop.)
Pull a Mr. Robot (not currently streaming on Netflix, sadly) and hack the site's search function by typing one of the many super-specific hidden category codes available here where you see the number signs in this URL: www.netflix.com/browse/genre/###/. From "Satanic Stories" to "Dutch movies" to "Foreign Gay & Lesbian Movies," there's a category to satisfy every niche viewing taste. You're welcome, all you Dutch-speaking LGBT satanist film-buffs out there.
