Reviews for Australia were as bad as Valkyrie, and I enjoyed it as well.
Ditto for my lady and myself as well! Yes, it did seem strange at first for Cruise and the other actors to not use phony German accents, but it was one less distraction from the dialogue. Which, by the way, is darned soft. I recommend sitting in the front half of the theater, and being prepared to cover your ears during the relatively few loud scenes.
