Not since Mr. and Mrs. Smith has a screenwriter tried to bolt so much violence onto a rom-com chassis.

**mild spoilers ahead*** This is one of those films that's almost more psychology experiment than entertainment, trying to see how far your suspension of disbelief can be stretched before it snaps.

For instance, can two people on a date eat hot dogs together then go snuff out some thugs? Sure, why not? Can a couple make out by throwing knives at each other's heads to see if they have a kindred level of eye-hand coordination? Kinky, but we'll allow it.

Anna Kendrick seems to be channeling Jesse Eisenberg throughout, though she is far too adorable and quick-witted for us to hold that against her. But the great Sam Rockwell is what this flick is all about. He's the reason to watch it from start to finish. Talk about "Mr. Right," here is an actor who makes everything right about every movie he's in, every time. Even one in which he is 17 years older than his leading lady! Hm...kinky, but we'll allow it.

Max Landis' writing is unique and has both hits and misses. This movie succeeds in part with the impressive tonal shifts in the story as well as some original characters.

The movie plays like a Diablo Cody-thing gone off the rails, which is a good thing, if you're prepared for that kind of stuff.

The action was unexpectedly well executed, but hard to really be engaged with because of the chaotic approach to genre.

If you're into something light and fun and tired of the tropes being played over and over again, then this is the next film, you should watch.
