I think TNG is one of those rare examples of a tv show where if you put any two characters together, they make a good double act.
With the exception of Dr Craptastic from season 2. Really did not like her.
Really? Oh, I love
Dr. Pulaski. She was a great foil for Data and a sister in arms for Worf. She also clashed with Picard, which was a nice change of pace up to that point.
