Re: reverse the polarity of the neutron flow
In the old days the scripts took the place of the special effects. These days it almosts seems like the special effects are included to take your mind off just how flimsy some of the plots actually are.
It's a shame Moffat et al seem enamoured more of making it into a spectacle than a serious series. Plot howlers are ignored; continuity is just a knowing wink to the original series to make the die-hard fan squee for a few seconds.
I remember Ray Cusick's response to the rebooted Daleks asking why this advanced race, time-travel capable and almost impossible to destroy, should still be using bolts and rivets on their casing.
(Yeah, ok - don't remind me of Troughton's Cybermen having lace-up boots...)
