How do I get over my phobia of watching dead people on my TV?

My mom recently bought the first series of an old 60's TV show called 'Bewitched' since it was her favorite childhood show. We watched it together and I found it kinda funny and the main character (Elizabeth Montgomery) hot. I went on the internet afterwards to see what all the cast was doing now, only to find they all died. Now I can't watch it. I find it morbid to sit watching a bunch of people who are now all dead. And I can't believe I thought a dead woman was hot. Am I strange?
