Six months before Katie and Micah are terrorised by a demonic force in their own home (as documented in Paranormal Activity), Katie's sister Kristi (Sprague Grayden) and her family suffer from a series of similar terrifying supernatural occurrences that appear to be focused around toddler Hunter.
Having recently watched the first Paranormal Activity, I was keen to discover what new tricks the film-makers had devised to ensure that the prequel remained fresh and unpredictable. In short: they hadn't! With the exception of some preposterous exposition in an effort to link the plot of Paranormal Activity 2 with events in the original, the format of this film is virtually identical to the first, only a lot more monotonous.
Once again, the action consists of spliced together video footage, primarily from the series of security cameras installed in Kristi's luxurious home after an apparent break in, but also from the hand-held camera belonging to her teenage stepdaughter Ali (Molly Ephraim). As the supernatural events escalate, Ali desperately tries to convince her sceptical father Daniel (Brian Boland) that something is terribly wrong in their home (apart from the fact that the parents let an Alsation sleep in the baby's room and haven't installed stair gates!).
For much of the time Paranormal Activity 2 feels like the cinematic equivalent of a Where's Wally book, only instead of wasting time searching for a bespectacled man in a stripy outfit, the idea is to try and spot almost imperceptible movement in an otherwise seemingly static environment, the most likely result of which will be eye-strain rather than abject terror.
After much unspectacular supernatural malarkey, the malevolent demon finally musters up the energy to make more than a baby's mobile rotate slowly or a saucepan fall off a hook and delivers some genuinely effective scares (accompanied by very loud noises to wake up those who might have dozed off), but when all is said and done, this second movie is far too similar to its predecessor to be considered a worthwhile follow-up.
4.5 out of 10, rounded up to 5 for IMDb.
