I started my path with the Star Trek universe in the 90s. It was a great time with a lot of sci-fi tv shows. What I liked about it ? Great future aesthetic with simple costumes yet colorful , whole space with different stories from personal conflicts to universe problems and ideas of a greater future for humanity in general.
I rewatched The Next Generation a few years back and this still holds…even more if you have in mind what is happening in the world. Some episodes still hold their ground and are relevant after all these years.
