My friend watched Chalk. He saw David Bamber and said that he had nightmares. The show was that bad.
Although David Bamber didn't do it alone. The entire show was a complete failure. Saying that the fact that it had an ongoing understated and unconsummated love affair going on made it like an American sitcom is hogwash! American sitcoms would never have a married man carry on so unless his wife was insane and never actually appeared on-screen. Even if they did, the fact that David Bamber was one half of this couple makes it highly implausible. We were already asked to transcend the lines of plausible reality when we were asked to believe that any woman would marry him. To think that another female would be attracted to him is impossible to swallow.
If anyone else had been in the role of Slatt, this show might have been palatable. However, it was not to be. I conclude by saying that this show should carry a warning label- avoid at all costs!
