Started strong but jumped the ship.
Killing off Clay was a bad choice. That's why Sean had to go as well.
Glen's character wasn't totally needed after awhile. Spencer and Clay's stories ran the show more. Also the siblings started out close and then grew a part way too fast. They should have been there for each other more. We could see they loved each other but they needed more bonding moments.
I think Spencer and Ashley were a forced couple. They worked better as friends. They paralleled Sean and Clay. Sean taught Clay to be black, and Ashley taught Spencer how to deal with her sexuality. It was two friendships. Ashley couldn't always be teaching someone. Ashley needed Spencer as a friend, to be there when she missed her Dad. As for dating she needed someone more on her level. I think Spencer was more in love with Ashley anyways. Ashley was less into it.
Spoilers:
They got together, but their story line was all over the place.
