God, this episode was pretty shitty!
Firstly the cutesy little fat babies was just too kiddy friendly for my tastes.

Tate was fucking annoying.
I mean, the whole bit where she is hanging asking for help, then when Doc helps her, she tells him to get off.....why?
It was neither funny nor made any sense!

Bernard Cribbins as the mad old man looking for aliens was just a gay set up for Tate to waffle on about how her life is unfulfilled (and the bit at the end with her in the Tardis waving at him made me vomit from all the sugary essence it gave off)!

The bit with the news reporter constantly getting tied up, was funny though!

I kinda zoned out when Tate talked at any point with her over pronouced common London accent and her constant facial contortions, so I missed exactly why she was investigating the company.

Also, in the dumb stakes was two incidents involving the sonic pen.
Firstly, if The Doctor really had no idea what would happen if two sonic devices were put together, why would he do it?
For all he knew, it could have killed himself, or caused the world to explode of something.
Mabe it can be written off as he did know really, but was just being flippant!

The second thing though was when he discarded it in a bin.
Oh yeah, thats an intelligent way of disposing of a powerful device/weapon.

Tennant, I liked as usual, but so much of his time was spent mooning over Martha and Rose!

I seriously hope this is not how the series is gonna continue!
