I liked this movie, it’s a fun sort of solidly-second-rate sci-fi-ish thriller about a group of wannabe startup kids who find a mirror in a hidden room in their house that allows travel to parallel dimensions. Soon enough they bringing back advanced technology from the parallel dimensions, copying the art they find and presenting it as their own, and soon they’re making money, and of course things get complicated.
It’s unassuming enough, not great by a longshot, but as it goes along it comes up with enough twists and turns to be entertaining, as long as you can tolerate the predominant douchebag startup personalities.
