Fantastic serial that's lightyears ahead of the four that came before this. I know there was much improvisation because they didn't really have a script, but it manages to eliminate the biggest flaw the series had at this point: stories being drawn out for too long, and it being too slow for its own good. The faster pace and condensed storylines makes this by far the most enjoyable serial so far. I also love how easily Ian and Barbara can manage to carry two entire episodes without the doctor, significantly strengthening their role as a companion (too bad Susan remains to be little more than a plot-device).
Easily recommended over the previous serials for people who are trying to get into Classic Who. Lot of fun.
