@Jules I love Star Trek: Discovery. First two episodes are quite somber, but from E03 on, it's Star Trek at the best it's ever been for me.
I recently rewatched Star Trek: Voyager, which has always been a favorite of mine, so if you haven't seen it yet, I recommend it.
Another movie I enjoyed was "Divergent". There are two sequels - "Allegiant" and "Insurgent" - but I didn't see them yet.
If you enjoy something grittier, the "Ghost in the shell" anime series is great, too.
