I always find with Bidmead, that he had brilliant ideas and brilliant stories, but had trouble translating them well to whatever medium he was using. He also couldnt characterise at all and most of his characters came off very one dimensional. If you could look past all of that then you usually were left with a very satisfying plot.
I totally agree and I think that was the problem with the last season of Tom Bakers Doctor. Bidmead had a strong sense of a good story. He has some lovely, novel ideas but the problem is, he just can't make them dance in the way Eric Saward, Bob Holmes or (laterly) RTD and Moff can do. Logopolis encapsulates all of those issues. If Bidmead had submitted these stories when Andrew Cartmell or Eric Saward had been script editor, I think we'd have had an even better product. Nonetheless, I think this release is still a very interesting piece of Who history and shows a brave attempt to redirect the show
