I have mixed feelings about TNG.
Being a TOS fanatic, I immediately hated it. Over time, they got a little better though. At first they were extremely 2-dimensional, simplistic, perfect, demi-gods without doubts or flaws. Yawn....
Later, the characters developed more complexity and depth. They also figured out you can't have drama without conflict and it gets boring to watch them cruise around the galaxy and resolve their differences through negotiation all the time. Sometimes you need to open up a can of whoooopasz!
I have developed a scientific method of determining if a rerun of TNG is going to be worth watching. You simple have to see if Riker has a beard or not. If Riker is beardless; don't bother. If he is whiskered then you might have a chance at it being a decent epsiode.
