I loved the movie, both Hellen Mirren and Ian Mckellan are great, the performance of Hellen as Betty is a little plasticky at the beginning, but that's exactly the point, she was "pretending" to be plain Betty, when at the end she outsmarted Roy the con, and she ends up being the good liar. She lived a good life despite all the damage Roy caused to her family, and vengeance is a dish best served cold.
