The story was supposed to be good, and the cast is definitely good, however it just wasn't as entertaining as it could've been. I blame the editing, it just doesn't keep the momentum going, sometimes you can feel a funny note coming but it drags too long so you lose anticipation.
Also they rely on Melissa too much for most of the scenes, they lose a lot of sparkles interactions with other actors could've created, I feel the whole movie I was watching one person doing and saying things, other people didn't really have to exist.
I started watching it at lunch, went back to working, and finished it at dinner, it didn't stay in my mind between the meals or after I finished it. Good time killer but not something I'd watch again.
