You could add The Newsreader.
Although a hit in Australia, it hasn't been shown much love from the UK audience despite critical acclaim. The first series aired on Sunday nights, but the overnight ratings were poor, with episodes rating lower than Songs of Praise, a concern for the BBC considering Songs of Praise did not get promotion, a plug on 5 Live's Must Watch and the pick of the day in the TV magazines like The Newsreader got, not helped by the series dropped in one go.
The second series is not airing on Sundays and is airing instead on Thursday and Friday nights at the moment against the C5 dramas and Big Brother. (The Sunday slot has been given to a Liz Bonnin show instead).
I think the main problem why The Newsreader hasn't resonated in the UK is the audience is seeing the real life behind the scenes shenanigans with GB News, Talk TV, the real life dramas of BBC newsreaders etc, and so no need to see a make believe behind the scenes drama about it (even if the acting is superb).
Hasn't helped that serious dramas set in the world of TV news haven't been hits in the UK (Making News didn't last long, E.N.G was short lived, and The Newsroom was aired to a tiny audience). And yet comedies using a TV news premise like The Day Today have been hits.
