Still paying for it: 'Grave Encounters' TW On Demand.
Found footage... such a tricky canvas. When it works, if you are into it, it's at least partly because it *looks* somewhat authentic: non-acting, effects, a kind of logic to its existence and reveal. The thing is when working with a new chain on an old bar there's a serious risk of binding up the saw: and the kickback can be messy. The new chain here is HD recording, oiled with cheap overly-ambitious FX, cutting into balsa.
Perhaps the conceit for 'Grave Encounters' is the meta-mocumentary: the juxtapositions of self-referential irony, modern film structure, and found footage narrative. This is incredibly difficult to pull off, as it requires a deep sense of internally-consistent logic and demands significant buy in from the audience.*
'Grave Encounters' is nothing more than wink-wink, nudge-nudge cleverness, delivered with all the tact of a pneumatic bolt to the skull, and without a basin for a tidy bleed. 'Grave Encounters' starts off strong: looks good, sounds good, is good. At about the half way point two things happen that begin the bind-up.
The first choke point is the fizzling of the story. There's not enough meat to carry 90+ minutes. It's half a slab of ribs, and sadly moves from homage to directly derivative of better entries. However, there are some decent chills (funhouse variety, and TxHF likes 'em) and rising tension. It's a creepy abandoned haunted insane asylum, a la House on Haunted Hill (1999), a TxHF fave: that SHOULD be plenty scary. So it is for a bit, and there is a dry and effective satirical stripe to hold some interest early on.
The second, and returning to the HD concerns, is the beginning of a string of laughably bad CGI/compositing effects: a big not-scary flash of light, which is supposedly supernatural wrath. HD is unforgiving of the badly blended compositing because there are more lines of resolution and more frames: it just stands out like a severed thumb on a birthday cake.
At any rate, it all finally ends. If you paid to see it, you may want your money back. If you got the idea it was badass because it was at Tribeca, remember that it's easy to end up bloated and ill from eating festival fare. You may also wonder, given the ending, a) where the fake crew found atomic batteries for the lights & cameras, not to mention the apparently never ending tapes; b) who found and mailed the footage to the producers; and c) why the producers didn't mark it Return to Sender.
TxHF gives it a grade of Lunch Meat.
*Unclear on the concept of good v. bad meta-moc? Very well, by way of comparison:
'Undocumented' does the meta-moc to great effect; as does 'Behind the Mask: The Rise of Leslie Vernon'. Check those out before bothering with 'Grave Encounters'.
