17. The Eleventh Doctor's Manic Debut
From: "The Eleventh Hour"
Premiere: April 3, 2010
Crash-landing in the garden behind the home of perky, lonely Amelia Pond (Caitlin Blackwood), the newly regenerated Eleventh Doctor finds a mysterious crack in the little girl's wall – an apparition that will linger throughout Matt Smith's tenure. His manic energy, a combination of Second Doctor Patrick Troughton's gentle slapstick and his own gangly, youthful zeal, create an instant charm. Leaving her for what he thinks is a moment, he returns 12 years later to encounter the 19-year-old Amy Pond (Karen Gillan). Yet even as their relationship deepens in later episodes and seasons, you sense that in some ways the Doctor is always relating to a wishful seven-year-old playmate abandoned with her suitcase.
