"For Jennifer" technically is a sequel to the 2013 jaw-clinching intense horror "To Jennifer", but it is meta enough to stand independently- in case you haven't seen the aforementioned flick. Told in a mock documentary style the story keeps with the original concept of extreme obsession that leads to a deadly end. This time the obsession is making a horror movie based on a faux film about the original film that went horribly wrong.
No personally, even though I enjoyed this film, it didn't have that dark, nightmarish realism that "To Jennifer" had. This is a good sequel in the sense that the narrative moves the franchise forward, creates a new story line, and possibly sets things up for more sequels. There is more twisted humor in "For Jennifer" that reminds me of later 80's horror .
The acting is pretty decent. The cast seem to know there characters and feel authentic. And like I said earlier, the story is fresh enough that it moves things in the franchise forward. That doesn't mean that the concept is totally original because a lot of the concept has been done before in found footage/mockumentary format. Still it is done well enough that it is entertaining.
The horror elements in "For Jennifer" comes later in the film but the body count rises in a bloody gory finally. The film's atmosphere is typical documentary style build up, creating an anticipation. Whether or not the playoff is worth it will depend on individual viewers. I personally thought it was worth the wait and since the practical effects were done with quality I enjoyed the last act a lot. "For Jennifer" is worth the watch, it isn't "To Jennifer" but it isn't really trying to be.
