it was a fact that when ever the doctor regenerates he becomes in a state of loopyness.

I can't help but wonder how does the regeneration energy apparently damage the TARDIS? and how did Matt Smith seem to be almost "excited" at the TARDIS being badly damaged and crashing towards the earth? curious thinking behind writing and filming that scene I must say - David will be sorely missed no doubt, but I for one have a great curiosity as how that scene and following series 5 opener will play out later in the year (usually around easter time)

I think the Doctor is just suffering from post regeneration madness.

Christopher Eccleston and David Tennant the best Doctor Who actors.. Can not wait to see new seasons of Doctor Who :-)

So the doctor gets angry and destroys his own TARDIS? Wow I think Matt Smith will be a great 11th Doctor!
