Talk to any fan of just about anything and they're guaranteed to have their favourites, and their not so favourites. Sports teams, video games, television shows, you name it. Doctor Who has been around for 51 years, with 13 different people playing the role of the Doctor. With each actor to star in the reputable role has come differing personas as to who the Doctor truly is. At first, he was an older looking man who was rough around the edges and generally "cranky", but softened as those around him got to know him better. From there fans have seen cosmic hobos, Dandies, complete goofs, serious tones, taking us all the way back to our incumbent Time Lord who once again, again, for lack of a better word, is "cranky". In the midst of all those personality changes, one Doctor in particular seemed to sum up all the differing attitudes and ways of thought that been commonplace throughout his previous incarnations, that being the Tenth Doctor, as played by David Tennant. While many fans have him, at worst, #2 on their own personal "favourite Doctor" list, this incarnation of TV's favourite Time Lord has shown that he is actually no better than many of his former selves. So, be sure to put those pitchforks away as it's time to countdown 10 reasons why the Tenth Doctor isn't all he's cracked up to be after all. Actually, he totally sucks.
