I thoroughly enjoyed this.
Though you can tell it's an indie production, the acting is solid, the visuals work for the setting, the plot (though low on in your face scares) is consistent and enjoyable.
If you want gore or a jumpscare every 7 minutes then Ghost Crew won't be for you but if you're after a film that features a paced build up, that feels like it's making the protagonist a little mad in his pursuit of the supernatural then I would give this a whole hearted recommendation.
But more Ghost Crew shows you don't need a film to be full on horrific imagery every few minutes to be scary.
The cast and crew should be proud of what they've done here.
That's not to say the film is perfect of course, but you don't need to be perfect to be good.
