Comment watching the old series (Score 2) 655
You should be aware that there are episodes that were lost in fires etc. So if you start from the beginning, you might be disappointed. Starting from the new series (2005) is probably OK for the uninitiated. If you watch the old series, you have to be prepared to watch some cheap sets and bad writing. Most of the sets were done with cellophane and papier mache. It is fun to watch, but if you watch the "confidential" series, the commentary refers back to the old series, where necessary.
