Review of Arachnids in the UK

I put off watching this show for a long time. I loved the ninth, tenth, and eleventh doctors so much and couldn't bear the thought of Peter Capaldi and his mushmouth diction. But this has me missing the good old days of Capaldi's skull-like visage delivering lines which were often very clearly written for Matt Smith's doctor and not for the grumpy and ridiculous rock-and-roll persona they were trying (and failing) to build. He might have been boring and cringey, but least I didn't feel like he was insulting my intelligence. But this? It just keeps getting dumber, like it was written by a bunch of high school sophomores who think they understand the world but are actually about a teaspoon deep. The stories are juvenile, trite, cartoonish, and cliched. They don't think. They just plop out onto the rug like the leavings of an untrained puppy. It's just a bunch of people solving a ridiculously contrived mystery which fails utterly to hook the viewer. The Tardis becomes the Scooby Doo Mystery Machine van without the benefit of steering. I want to be able to finish the series but I've got no reason to believe it will improve.
