Production Errors

  1. Isn't it 'theoretically' impossible for Terminus to be at the exact centre of the known Universe. If the Universe does in fact expand, then wouldn't Terminus have to continually change its position, to take into account the expanding Universe and the location it's currently in?​​

Working Titles

If there was ever a Doctor Who story which should receive more recognition and praise for its worth then that distinction should be this one. Tightly designed and written. The production design is top notch with tucked away doors and corridors and darkly lit corners. The sinister nature of the sets are assisted with slow camera movements which create a claustrophobic atmosphere for everyone involved. The exact centre of the Universe plot point matches surprising well with the Big Bang plot point, the third in the Peter Davison era to do thus. Some well structed stunts and executed practical explosions add to the tense story. The Black Guardian is a little unbelievable he would not give Turlough so many last chances as he does. Nyssa reaches her highest point in the serial and her departure is one of the series’ saddest exits you can really tell The Doctor loses someone very special to him and the unrealised epic duo will never be been seen again. Tegan and Turlough continue to get in each other’s way. Not the prettiest of serials to watch but it is certainly a rare treat. ****​
