4. Luke – GROWING PAINS
I understand the reason why the producers of GROWING PAINS introduced homeless teen Luke (played by future movie star Leonardo DiCaprio) in what turned out to be the show’s final season. The guy playing youngest child Ben grew into a decidedly goofy looking teenager and Kurt Cameron, aside from being too old for Tiger Beat, had gone fully around the bend with his deep, deep love for his Lord and Savior Jesus Christ. So a new teen heart-throb was needed to keep the show happening with the younger demographic. The problem was that Luke never fit in any way shape or form on the show. No matter how they tried to integrate him into the family dynamic the character always stood out like a sore thumb.
