The morality of revenge has been used as theme in many occasions, Kevin Bacon and Jodie Foster have made similar works before. While it doesn't necessarily innovate crime genre, Lila & Eve works by displaying the intimate issue with strong performance. It's a story about two mothers seeking justice, yet ultimately absorbed by the vengeance in an attempt to cope with the overwhelming sadness.
Viola Davis as Lila is easily the best asset of the movie. She's completely believable as the grieving mother, often seen hurt and confused in highly sympathetic manner. She can draw audience interest and even suspense judgment as she dabbles in less savory acts. Since the movie almost entirely revolves around her trial, it's a boon to have a reliable lead.
Jennifer Lopez has a mixed record in acting. There are a couple of good movies when she delivered, but most of the material she worked were mismatches. The most advantage she has is she can appear to be not glamorous, as in Parker and The Boy Next Door. With Viola Davis, the chemistry is definitely present, she appears to be an integral part of Lila's story than just a guest star.
The movie is not without flaws though. It's hampered with a few crude developments. They can be a bit problematic, although not entirely jumping towards one-man-army action theme or overly bloody violence. Furthermore, the plot twist it tries to pull is predictable and it could've been more refined or subtle in its delivery.
Unfortunately, many elements of the movie are notoriously cliché. The vigilante thriller and the chasing cop aspect feel much too familiar. However, Lila & Eve has enough private sentiment to be emotionally engaging even though the cause might not be just.
