i simply can not understand how any who fan and or just plain anyone could find this awful and lazy and poorly write abomination even remotely funny . it be so embarrassingly below par that it qualify a a genuine tragedy . the potential for this be huge and it could have be great . what a shame that all that act talent and the set and the prop and the goodwill of everyone involve be so pathetically waste by a script that should have be burn . there be an obvious lack of any rigorous production and quality control here . like those hammy hollywood movie ( mad mad mad world and casino royale ) where the star be just mug for each other and have a great time which basically mean pick up a cheque for do nothing . i could have write a good who send up in my sleep . in fact i have and while awake though . i do it in year 10 in high school and perform it with a bunch of classmate . it be well and i look at it now and the gag be funnier . steven moffat you be a no talent bum . what a waste and what a wasted opportunity . make me want to cry .
