I personally really like these:
- Dark (It's a German sci/fi series about time, which has the most mind-bending and mind-blowing plot ever!! Really recommend if you like to actually think while your watching, and trust me even how crazy it gets, it'll all makes sense and it's and everything ends up being well explained the end. And for once the ending is not predictable and disappointing at all!!! One thing though if you watch it, PLEASSE watch it subbed and not dubbed, it really ruins the vibe of the show)
- Gravity Falls (Just the greatest animation series of all time!!!!)
- Game of Thrones(though only season 1-5, the rest is a disgrace a should not be mentioned)
