Christopher, I watched the Reeve series pilot just the other day. Pa has a heart attack and dies on the anniversary of the day they found Clark, as he's headed to clean up for the celebration dinner.
The acting was horrific, by the way.
I think Returns would have been better without the CGI flying closeups. Not good. Also, until yesterday I didn't know that Routh was wearing blue (-ish) contacts. I always thought his eyes were their natural brown color.
