The Guest

The Guest ★★★½

How I imagine most of Maika Monroe's auditions going
Maika: So, is it a pseudo-retro genre flick with a killer soundtrack?
Casting director: Well, no, not really.
Maika: Then why the hell am I here? *storms out*

The Guest is essentially reverse Rambo; veteran is accepted by society, still kills entire town. However, The Guest plays better, owning it's fun B-movie thrills with cinematic verve. Good time all around.
