Sometimes we quit watching a miniseries

I don't chronicle every miniseries that we start to watch and then abandon - there are lots of them! (most recently the Japanese Midnight Diner, a cool idea - late-night chef meets various people in his restaurant, each w/ a tale - that translates poorly from Japanese culture to American - but sometimes when we're drawn into a few episodes before we jump ship it's worth at least a mention, and that's where we are with the British comedy, now in Season 3?, Catastrophe. The story - about a couple that meet in a London bar (he's a visiting American businessman), have sex, stay together for a few days of sexual adventure, then he goes home to the U.S. and she calls him shortly thereafter to inform him she's pregnant. She plans to deliver and mother the child - she in her late 30s and senses the bio clock - and he, being a mensch, agrees to come back to London and work things out; soon, they're engaged - but they hardly know each other. That's the premise from the first episode, which was cute and funny at times, and the 2 leads are very likable - but by the end of ep 3 we had to wonder where this series was going. They quickly ran out of narrative ideas, it seems. He meets some of her family and so-called friends, all of whom are extremely unlikable. We get a little bit about the professional lives of the 2, she a schoolteacher and he an ad salesman for a small NYC firm, but their careers seem to play only a minor role in the story line. Many of the scenes, though broadly comic, are not at all credible - Why would this nice man have such an idiotic lout s his best buddy in London?, for ex. We can suspend a ton of disbelief for a good comedy, but it's important that we buy into the lives of the central characters, no matter how eccentric. In this one, we have to wonder: Why do these attractive, successful, witty adults seem to have virtually no life outside of each other? Things don't work that way - except in the movies, so to speak.
