Lets remember how bad the first two seasons of TNG were when Gene was the showrunner, he was still doing the show like it was stuck in the 60s!
Except with a lot less censorship.
And actually Roddenberry was only the showrunner in season 1. It was Maurice Hurley in season 2.
Hurley was the sole showrunner for season 2? Really? You learn something new everyday!
