In 'Taken', Bryan Mills (Liam Neeson) rescued his daughter from kidnappers, and killed quite a few bad guys in the process. Well their family is back for revenge, and Bryan once again has to rescue his family from kidnappers using his "particular set of skills".
Liam is again excellent as Bryan. Not too much of a plot, but lots of action. His daughter Kim is particularly helpful to him this time.
Content warning would include violence. There is plenty of shooting, but not a lot of gore. PG13 is an appropriate rating.
As with any sequel, I couldn't help but compare the two, and to be honest, I would give the edge to the first Taken. But If you liked the first Taken, you'll really like Taken 2.
