Too true about the Networks, also there was a HUGE pressure not to be "dangerous" in examining conditions, shall we say, "to close to home" at the time,... and therefore exploration of ourselves and our values were somewhat squashed in the interest of not offending the 'accepted political party lines' and the sponsors.
On a personal note:
I would have loved to have seen more military-based operations, but again, here comes either the Prime Directive or The Organians.
When I first saw the episode: Arena
, I thought: FINALLY we are going to see these guys in a full-scale ground-assault fire-fight,... but no,... a Metron crashed the party.
