Star Trek was action/adventure/scifi with strong characters. The only difference thus far between Abrams movies and the original 1964 pitch is that the Enterprise ain't doing much exploring at the moment :P
Actually, Kirk didn't do much exploring of strange new worlds in ST II, IV, V, VI or "Generations" either.
JJ's "Star Trek (2009)" was "action/adventure/scifi with strong characters".
I am damn sure Roddenberry would have had lots of action in TOS if he could afford it...
He could afford it with ST:TMP and TNG's "Encounter at Farpoint". Huge budgets! Both of them are high on talk and low on action.
