I’ve always liked Olga Kurylenko; I was initially drawn to her performance in _Hitman_, and she's a significant reason why I enjoy that film. I saw her in other roles afterward before she really stood out in _Centurion_. When news broke about a horror movie starring Kurylenko in 2018, I was eager to see it, especially since Craig Conway also appeared! That made my decision for me; there was no way I’d skip _Mara_. However, despite both actors delivering solid performances, I realize now that I focused too much on the fact that I like them and not enough on things like the plot description. Because _Mara_ feels like just another one in a wave of very similar (and generally unsuccessful) horror movies dealing with sleep paralysis. It might be slightly better made than some of its counterparts, but it’s still as uninspired as the rest. _Final rating:★★ - There were elements that I found appealing, but ultimately the film didn't quite work._
