I'm not sure why the rating for 70 Big Ones is so modest because this is a really decent movie.
There's a clever symmetry to this tale of crime and love for family, that does require you pay attention. If you do, you will be rewarded with a reveal, that shows that things are not always as they seem and the lengths, even broken people will go to, to protect those they care about the most.
Acting is top notch, with a cast of actors, I'm familiar with from other series and films.
In summary, clever in its simplicity, engrossing and touching. Take a look, you wont be disappointed.
