Well the Child is just an absurd episode that really falls in the lines of what the hell? So this space tinker bell pretty much makes first contact with species by raping women and then being born as one of them. I don't know if that is more disturbing or the fact that everyone was perfectly fine with it. Save Riker, who was just petty and jealous, and Worf who just wanted to kill something.
As for the Crusher/Pulaski change? Well Crusher... I find it funny she just left Wesley there. Not that I blame her even if that is dead-beat parenting. Though I guess if you go for the theory that Picard is his dad, then one parent was still around. As for Pulaski? I can't say I cared for her too much, but she did bring one thing to the crew that was missing. Drama and conflict. Everyone in TNG is too hunky dory in their clique bubble and it's nice every now and then to see an outsider shake things up.
