it's a shame the viewing figures are not that good. Unfortunately, sticking to the years that are being shown is going to limit the audience size too. To appeal to a bigger audience they need to have a wider selection of years, but obviously technical limitations and cost are not going to help.
I hope it does work out though and viewing figures increase to a worthwhile level. I only found out about the shows about a month ago, there could be many others out there who would be interested but don't visit internet message boards and don't know that the reruns are being shown.
