There's no way of putting it mildly. Demon Baby is barely passable as a family vacation video. Take a few actors in camping site, make them act with inconsistent script and call it a movie. The entire short length of the movie is Rose having pregnancy scare, she's moody and grumpy while Theo plays the compassionate lover role. For those hoping for good psychological twist or any coherency at all, the movie will disappoint.
It delivers little to no depth, not to mention the narrative stumbles around like Rose actually does on-screen. With barely over an hour runtime, much of it is spent in slow pace bantering and resulting in timid scare at best. It can't decide if it opts for possession, usual haunting or psychological breakdown, so it mashes all tidbits and creates a shoddy excuse for thriller.
If there's anything, at least the view is kind of nice and the actors do try. Soundtracks remind me of Silent Hill, not bad considering the limited production value. Honestly, this looks like a tryout in local cinema or the director's personal tape. Highly not recommended.
