Genya (2010)

if you like one you will definitely like the other both have female lead villains and an unusual type of plot

Questionable female leads, naive male leads.
In Genya's case, the female lead is the source of a lot of crime and killings, whereas in Ice World, the female lead is framed into looking just as bad. There are over-passionate cops trying to take down the FLs in both as well.
