Hmm…well it depends on what you want. I like sci fi but if you want a series that makes you genuinely care about the characters and explore the human condition, I recommend Battlestar Galactica. Its definitely explores a lot of philosophical themes.
The Three Stooges, Buffy the Vampire Slayer, Once Upon A Time, Teen Titans, Lucifer (heard it’s good), Sabrina The Teenage Witch, Avatar the Last Airbender,True Crime Daily, NCIS, RWBY, Miraculous Ladybug, Black Butler & I heard that LOTR is getting a series omg
Screech was pretty cool too, actor not so much. I just always loved Mario Lopez and Slator was just everything. Also as a dancer, his whole dance scene was everything.
LOVED Buffy, Once upon a time I used to watch but it stopped after a while and idk. Watched the first episode of Lucifer wasn’t really my thing, but maybe it just takes a bit to get into it
Nothing is unhealthy when it comes to LOTR, I say watch it soooo many times, J. R. R. Tolkien was & remains a freaking genius I wish I could have met him
