Why is modern Star Trek so violent and empty spectacle?

I grew up watching Star Trek and its spin-off TNG. Starfleet was primarily concerned with exploration and each episode carefully explored the ethical dimension to events. Violence for its own sake was not a part of the storyline. There was a realism in Star Trek, I found lacking in the simplistic morality tale of Star Wars.

Yet from what I've seen of modern Star Trek it's violent even ultraviolent with little or no emphasis on cerebral plotting, instead focusing on empty special effects laden spectacle.

This is what happens when young people are given creative control over beloved series such as Star Trek.

Star Trek died quietly after Voyager wind-up (and I didn't think much of the last few Voyager seasons). 'Enterprise' was a joke and those modern film versions with Chris Pine as Kirk should never have been made.
