The Other Side is a psychological thriller that went in a completely different direction than I was expecting it to, in a good way, and despite its length it never dragged or felt overlong. I knew I was enjoying it when I experienced second hand cringe during a group therapy scene.
Chris Mills is great at being compelling while playing a pretty terrible person with almost no redeeming qualities, and the times you do have to feel for Aaron he more than brings it. Peter Tilley is also a real one scene wonder in a key moment that's definitely the most gripping part of the film. I wouldn't be opposed to a 'sequel'/companion piece from Ross's POV. Amie Howes also provides quite the screen presence as a 'Lost Lenore' figure that would make Edgar Allen Poe himself applaud.
Overall a solid thriller with good production values, nice performances, and good directorial effort from Mitchell Burrows.
