I miss having shows that convey a feeling of hope for the future. The current mostly dystopian grimdark sci-fi is an easy way for unimaginative writers to make their world feel more real at the expense of destroying that hope.
It's sad that even the new Star Trek movies (post 2009) and shows courtesy of Alan Kurtzman and J.J. Abrams have completely lost that spirit of the previous Star Treks. Instead it's a bland insipid take on the Star Trek universe by people who have no clue of what makes Star Trek Star Trek and do not respect it.
