Most of the old Doctor Who episodes can be summarized as:
Through some accident, the Doctor teleports somewhere beside his intended place or time. He ends up in the middle of some bad science project or military situation. Everyone assumes he’s trying to sabotage their project or military situation. After his he and his assistants are captured and rescued several times, he finally convinces people that he knows what he’s doing and saves the day.
Throw in a lot of bad alien costumes, plodding dialog, and gravel quarries…not that any of this keeps me from watching it. 🙂
