Have yet to finish, but I don't like what they've done with Q.
He was an ass, but he was also usually in the right of it. They dialed the "god is a jerk" up to 11 and removed any of the cosmic wisdom or subtle guidance he used to possess.
Essentially he's become a psychopath with god powers. Which he never WAS, not really (In fact he clearly had great respect for Picard, as seen when he complimentef him on saving time and space yet again in the series finale)
Was a decent 1st episode, but it's riding on the back of a meh season 1 and a meh to just okay at times season 2, so I'm expecting it to turn sour soon enough.
They did put out ST: Strange New Worlds last (7 good eps, 2 okay ep & 1 shit ep), which was a breath of fresh air in what has been an otherwise cabbage-n-eggs fart riddled Star Trek basement, so hopefully I'm wrong and Picard S3 is great.
