Part of the story is standard thriller fare by now - the professional assassin becoming hunted. Some over-the-top action scenes there.
Another part is the dysfunctional but caring family, with guilt, remorse, love, drama. Well played, but it's an unusual combination with the assassin story; and this special mix will appeal to some people - but my guess is: not many.
Good actors giving good performances, solid work from other departments. But I don't think script and direction were bringing their A-game.
