love part one and the impossible planet and but whoop and what a disappointment part two the satan pit be . the cliffhanger of something apparently rise out of the pit be nothing come out of the pit . then age spend crawl round air vent to pad out the story and the beast a roar thing empty of intelligence and so no doctor or villain confrontation i would be anticipate . the tardis be somehow inside the pit despite the pit not be open till long after the tardis fell through the planet crust . and finally another ready make solution which exist for no logical reason i mean and why not plunge the beast into the hole as soon a the pit open . why not plunge him in all those year ago instead of imprison him anyway . why not i could go on but i have lose interest .
