A good idea underneath concerning the media sensation of the first, but it's a product of watering down its promise. The silly and annoying dialogue sticks out like a sore thumb in its cliquishness, while Berlinger's directing isn't scary, feeling like a product of an MTV video in its flashy editing and hollow scare-tactic style. Gone is the maturity and suggestion of the first, making it a horror film for teenagers.
Probably the biggest example of an experimental and creative film that was watered down and stripped of all intrigue in post by the studio. Who knows; perhaps if we had Berlinger's original vision, we could be viewing BW2 as a worthy sequel instead of the generic, confusing 2000's horror crap we have instead.
Not as bad as you've heard or might expect. The thesis of Berlinger's meta-sequel was always probably too smart for its own good: a cadre of BLAIR WITCH fans take a cash-in spook-show tour but slowly get sucked into a mass delusion that blurs fiction and reality. The studio's meddling is unfortunate but unsurprising, so the end result isn't what could have been...but there's a glimmer of something great underneath.
A truly terrible film and one of the worst "sequels" ever, but it gets an extra star for referencing "Titicut Follies" before the opening credits. After that, it's all downhill. Joe Berlinger should have stuck with freeing the WM3, at least he did something useful then.
