Having seen the movie, these titles of "The Last Girl" or "Cult Killer" (having two is not a good sign) seem absurd and are no doubt part of the reason why some reviewers give such low ratings, as their expectations were not met by reading too much into them.
Something like "Revenge of the Abused" or "The Playhouse" would have been far more suitable.
Overall the movie held my attention as it had an unusual enough premise and I wanted to see how it concluded. It could have been more of a thriller, but lacked enough plot twists and reveals for that, which is not to say there were nonesuch.
There wasn't much by way of suspense, either, as you find out too much for that too soon, and the story becomes much more of a procedural. Indeed, it struck me that this could have been a feature-length pilot for a TV series about a female (English?) private investigator and recovering alcoholic, in Ireland, who sometimes works alongside the police (Garda). However I think the marketing may have screwed it up too much for anything like that. You certainly wouldn't expect Banderas or Eve in something like that. So it seems to have come across that way perhaps more by accident than design.
Alice Eve acquits herself fairly well, and you can certainly see how her character comes to identify with the killer she is pursuing (and vice-versa), but her 'badass' scenes and the character depth she provides are undone by the couple of scenes where she comes across as a genteel English Rose, especially at the end (Oh no!"), which stood out all the more in a movie with some brutal and bloody scenes, some of which her character was involved in. This left me wondering if she was not the first choice for the role, but they couldn't afford e.g. Kate Beckinsale. She just seems slightly miscast, or perhaps the best they could get for it and ultimately, despite some aspects of her performance, as not quite right for the role, at least in hindsight.
Hennig is very good in her role opposite Eve; her character was completely on-point, but the acting honours in this one go to Banderas, who is excellent as the mentor to Eve's character.
I was split between rating it 6/7 (13/20 perhaps?) and eventually decided to go down rather than up. Probably not a movie you would go out of your way for, but it's watchable if you do - so long as your expectations are not based on the appalingly given titles.
