Season 2 of the Trump Show has been really tedious. The show hit its stride last summer, when there was a lot of plot momentum — in fact, it almost became “appointment television,” as people tuned in around close-of-business every day to learn of the exciting new developments. But as so often happens in American television, what should have been a UK-style limited series has been indefinitely extended. The characters are so thin, and the setup so improbable, that we get nothing but the repetition of the same scenarios. The attempt to inject some lurid interest with the porn star theme feels desperate, and bringing back the Giuliani character is some kind of weird fan service for a fan who doesn’t really exist. The one genuine comic relief, Sean Spicer, has been replaced by perpetual wet blanket Sarah Huckabee Sanders — a major casting mistake, though an understandable one after the blow-up with the Scarramucci character.
