 We wanted to get away from the slightly flimsy look of the earlier series . So I beefed Davros up , made him more sturdy . I also think that the reinvented Davros is unusual for the new Doctor Who because he is genuinely grotesque . Sometimes we ’ ve held back a bit with the ugliness of the monsters . But Davros is a very unpleasant looking character , which makes his return all the more powerful .
