One of the advantages afforded to Television over the film industry is the opportunity to tell a story over a longer period of time. As a result, with the odd exception, I have generally preferred shows with an ongoing story to those with standalone episodes. Doctor Who fits pretty much completely into the category of one off episodes and so, for me at least, I never found myself drawn back to watch episode after episode in the way that some of the very best drama series have done.
Having said all that the Doctor's revival undeniably ranks amongst the best British sci-fi/dramas of modern times. Some episodes are certainly better than others, and the special effects aren't great on occasions, but the writing is generally very good across the entire series and Christopher Ecclestone and Billie Piper are always watchable in the lead roles. Never taking itself too seriously there are more than enough interesting and entertaining ideas here to please almost any sci-fi fan.
