Doctor Who!
The BEST T.V. SHOW EVER. Not to mention one of the longest ever. Over 50 years and still on the air. Its british what do you expect. So far there are eleven doctors. one character eleven actors.It all started when the first doctor decided to retire from acting. the show was such a big hit that they made an excuse to change actors and people loved it so much that from then on every few years they change doctors to keep the show fresh and exciting. there has been a brief hyatis in-between a few of the doctors.
