The Discovering Trek blog reflected my frustration at the use of Season 2 screen time to promote a new show. Section 31 will no doubt feature again but this episode was a little heavy handed. However it did make my think what's the best back door Pilot? A backdoor pilot is defined in the following way;
" backdoor pilot. A backdoor pilot is a movie or miniseries that serves as a proof of concept for a full series, but may be broadcast on its own even if the full series is not picked up. The term may also be used for an episode of a currently running show that serves to introduce a spin-off. "
I think my favourite show introduced in this way is Millenium a spin off from the X-files. What are your favourite successful or failed attempts at spin offs?
