plenty of weaknesses — an unevenness of tone, a
surfeit of plot convolutions, some problematic political echoes — but its central flaw is that it is absurdly, punishingly overlong.

surfeit of media organisations intent on burdening the public with «information» about climate change, journalists like Black were ten - a-penny.
