I watched that first season with Hagman but when he died I wasn't interested anymore. As soon as Hagman died that series was finished. He carried that show as the supporting new characters were weak in comparison to the original series. Patrick Duffy wasn't able to carry the new showon his own the way Hagman did. He didn't have the same presence on screen & his character Bobby was a nice guy. In the original series, he balanced off JR's ruthlessness & lack of morality. Without JR, Bobby was just a weak Goody Two Shoes.
Victoria Principal wasn't part of the new shoe & neither was Steve Kanaly who played Ray Krebbs on the original show. He was the half brother of Bobby & JR & he was looked down upon by JR who never considered him an equal or entitled to any of the estate of their father. Leaving Kanaly & Principal out were mistakes.
To me, the new series was okay but not great.
