The Tenth Doctor is, for many people, the definitive incarnation of the 900-year-old Time Lord. David Tennant's Doctor was charming, charismatic and dashing, with a fondness for smart suits and the immortal phrase "Allons-y" ("Let's Go", for you non-French speakers).
After only one year as the titular Time Lord he had already won over the fans, with Doctor Who Magazine readers voting him 'Best Doctor' above the usual favourite Tom Baker. So popular was Tennant that the BBC even debated axing Doctor Who when he announced his decision to quit the role.
However, despite his enduring popularity, Tennant had his fair share of naff scripts which could have done with another draft or two. For every Human Nature and Doomsday, there was an Evolution of the Daleks and Voyage of the Damned.
It speaks volumes about Tennant's devotion to the character that he managed to elevate even the most mundane of stories into a riveting adventure. Having said that, it is undeniable that even with the talent of such a leading man there is no redeeming some absolutely terrible episodes, some of which stood out like a sore thumb among the gems.
