Stalker movies are a subgenre in themselves — a good chunk of horror movies feature stalkers and stalkees and the really watchable ones (see 2005's "Dark Water") are heavily psychological, delving into the minds of certain people who get their kicks out of watching and harassing certain other people, 24/7.
"388 Arletta Avenue," however, isn't heavy on the psychology, or anything else for that matter. It seems to strive for a nice balance of terror, gore, some humor and healing. As far as stalker movies go this one is almost inoffensive, backpedaling from the brink of the truly horrible at every opportunity. If screaming at the screen at the top of the lungs is your thing, "388" may not be worth the visit.
The picture uses a found-footage format. This style of filmmaking, using video that is presented as incidental and amateur to make a story more believable and scary, broke through with 1999's "The Blair Witch Project," was put to outrageously imaginative use in 2008's "Cloverfield" and raked in box-office coin for the ongoing "Paranormal Activity" series.
