Doctor who season 4.

Everybody seemed to have their reservations about Catherine Tate playing The Doctors new companion, and most people said it was because they thought that she would be like one of her characters from the Catherine Tate show.

I can promise you she is not, her character far outshines Martha Jones in terms of depth and comedy, the pair are fantastic together, they are both hilariously funny and yet can be emotional enough to make my dad cry! With Donna Noble there was none of the constant pining that there was with Rose and none of the smarty pants attitude of Martha and for once it was nice to have a companion that was not madly in love with the Doctor!

Episode one was fantastically written and directed (even if they did drag out the pair missing each other for a little bit too long)

*JOURNEY'S END

*MUSIC OF THE SPHERES

The direction of season 4 is absolutely inspired, it's full to the brim with action, chases (lots of running!) explosions. It's atmospheric and the acting from all involved is incredible

Tennant can go from quirky and energetically insane to sinister and hurtful in the blink of an eye. Tate can switch from the no nonsense attitude to trying to instill some human compassion into the Doctor seamlessly.
The special effects on Doctor Who only evolve and get more breathtaking as time goes on. The time and effort involved must be amazing. My personal favourite effect was from THE STOLEN EARTH, The 26 planets in the sky just blew my mind!

In short, if you have still not watched this because of your reservations about Catherine Tate, give it a chance, she's nothing like any of her characters and nothing like Rose or Martha. You won't be disappointed
