In this episode a grown man (well, technically a built one) befriends a young girl without her parents knowing about it. He lies about who he is, visits her bedroom while her parents aren't around, kidnaps her and erases her memory.
Wait... what?!
Yeah, so this episode comes across as really really wrong to people living in the Internet age. And honestly, it was pretty disturbing even before that. The storyline itself is quite good and shows how messed up the Prime Directive is. Basically TNG is making excuses for the way the US conducts foreign policy. I'm pretty sure Picard would even let the Holocaust happen because of this dumb rule.
The other storyline is another "Wesley comes of age" plot. It isn't bad, though it does drag the episode down a bit. What is nice is that it shows Wesley to be insecure. Long gone are the days of Wunderkind Wesley. He turns out to be human after all. And so do Data, Pulaski and even Picard.
