I will give it this, though: the final scene of Matt Smith in the TARDIS was done well. If it was shown in a clip show of the Doctor's regenerations, it would look very good, in comparison to many others.
It's a pity that the ending was somewhat ruined by Capaldi's entrance, which oddly didn't have the standard morphing effect.
Then again, Davison's regeneration ends with Colin Baker trying to kill Peri... yet it's highly regarded, so go figure.
