"Britannia Mews" which also goes by the name "The Forbidden Street" is a nothing movie. Oh it tells a story, has a nice set and an appealing cast, well it stars Maureen O'Hara, but it is all kind of pointless. It is hard to describe without giving detail away but the story sort of goes well to do woman marries, suffers hardship, then tragedy but then receives a glimmer of hope of happiness again.
The thing is that everything else in "Britannia Mews" is fine and Maureen O'Hara delivers an enjoyable performance with an accent which takes a journey. Plus this movie features puppets and whilst you can see that it isn't Dana Andrews operating them the scenes featuring them work well. But the storyline just doesn't really grab your attention as it meanders along to a suitable ending but nothing special.
What this all boils down to is that "Britannia Mews" is a simple and charming drama which has everything other than a great storyline to make it compelling.
