First reviews trickling in: Indiewire calls it "almost a masterpiece," Empire compares it to ye olde Ealing comedies. The Guardian's review was more mixed and they also reveal the ending. I'm sure they won't be the last.
The AIC review didn't make it sound to hot.
So this didn't get picked up by anyone at Sundance for US distribution? I don't know who other than IFC might take a chance on it.
