Right? When I visit my family who live away, my first thought isn't "oh, I hope there's someone there I can date."
It just sort of sums up the point of some soaps, that if you're young, attractive and will look good alongside another cast member, you've got the job. The majority of the older cast members are only still there, I imagine, because they've been around a long time and are popular. The majority of the cast are young and attractive.
I am a massive fan of Neighbours, but some of the acting is just dire and obvious that they were hired on their looks and that just annoys me personally.
