Premise: “A group of friends stumble upon a mirror that serves as a portal to a “multiverse”, but soon discover that importing knowledge from the other side in order to better their lives brings increasingly dangerous consequences.”

My take: It’s a bit of a slow burn movie, but it has enough going on throughout that I never felt like it was just treading water. Worth a watch imho.
