Not to pee on the "I hate Huey's voice and diction" club, but I liked Chad's characterization. I think it added depth to a pretty vapid show that was trying to act like it was breaking new ground.
I think Huey was delayed or "slow" and both he and Felicia knew what it was like to be oppressed and underestimated. Both were looking for someone to see something else in them. It was also the reason the relationship couldn't last. She could never really stay with him and he knew that. Also, he found escape in music which is why he was so passionate about it. I think his choices gave the character some nice nuances.
