Its an ok film, with a good cast, worth a watch.

There is female nudity but violence is rather sub-par than prominent.

It's a bit underrated for my taste. I didn't need to suspend my disbelief constantly.

I guess you mean: "How bad is the violence and HOW GOOD is the sexuality nudity?"

As far as the nudity, it's brief: one scene of Plummer and Forster fully nude from the side view, then a scene with Plummer topless and Forster full-frontal.

Nothing really that gratuitous, considering the context of the scene involved.
