Not too bad...

Just watched it on Amazon Prime. I think the story was so-so, and I mostly liked Palmer and Robbins. MacDonald in particular didn't really play his part right. The others were off a bit, too. It was low budget, and I think the film fell victim to 'we got the important part' for a lot of scenes, but it never gave the cast time to really nail their parts. Because of that, the tone and mood are uneven, I never bought into most of the characters' motivation, and it feels like various acts of violence just happen, not that most of the characters are driven to do these things, so it never really came together.

It's too bad, because I think it's a decent story. Characters let themselves be put in stupid situations several times, and they don't finish each other off when they really should, so the logic falls apart. Address those issues, then with a few character tweaks, particularly a bit more detail to add to the backstory and characterization, it would be pretty solid. The acting is a bit more problematic. Palmer really needs to agonize over her decisions toward the end, and the big reveal needs to have more of an impact on her. Robbins may have been a bit too likeable, and at one point, you feel bad that he doesn't get a break after being such a 'nice guy' (in fact, he was SO likeable that I was wondering if he was going to try to romance her by the end!). MacDonald just isn't convincing. I never buy that he's a threat, so I have a hard time believing any of the characters are, or should be, scared of him. I think he's going for 'urbane criminal', but it really comes off more like 'well, it SAYS I hurt X in the script...'

It's too bad, since I've seen most of the actors in other things, and I've liked their work. I think the story was headed in the right direction. It just doesn't quite get there. I recommend 'Heat' for a number of similar themes, and even a few plot points and scenes that are similar.
