You may remamber Wll before TNG, working with River Phoenix in Stand By Me (1986).
Mark Hamill was also some sort of victim of his character, and got difficult to have decent roles after be the eternal Luke Skywalker.
Whesley Crusher wasn't a bad character, but the problem is that was not very well developed by the scriptwriters. This hurts a actor, cause it do not allow hin show his talent.
I like TNG first seasson, despit the many defects it have, the family feeling was nice. Not everything need to be always intelectual complex crazy neuron burn drama.
This world is desperateley in need of nice people.
