Greetings from Lithuania.
"Exists" (2014) is a not the best not the worst horror flick out there. Shoot in a "found footage" style it tells a story of a group of teen who found them self in the pursuit from Bigfoot. The acting was just OK for this material, but overall movie is quickly forgettable nor really intriguing. At the running time 1 h 17 min (it's kinda short movie) it barely drags, but there is no character development, so we don't really care who dies who lives.
Overall, "Exists" is just OK horror flick, quickly forgettable one, but kinda enjoyable while it lasts. The director is Eduardo Sánchez, who created the legendary horror flick "The Blair Witch Project" (and one of the most successful horror flicks ever). Here he comes back to the formula, but the result is not very successful.
