'huge, queer and tawdry' but 'much admired by the public'

I think the major problem with the Peake part, having watched it just, is that, while it mentioned his nervous breakdown, it incomprehensibly ignored his struggle with Parkinsons' Disease that crippled the writing of Titus Alone. Not only that, the programme didn't even mention that, partially because of that but also because of the change in setting, the third book is almost completely different. Surely the recurring theme of escape should have been mentioned, since Titus wants to escape, does, then finds himself in a world more horrible, incoherent and surreal than Gormenghast?
