Horror on $0 budget never works out. The film was cheesy. The "actors" were horrible. the "direction" was infuriatingly bad. I couldn't have more of the problem with the MST3k-fodder if I tried.
On top of all of that, the monster was the most unterrifying, and most easily escapable thing ever.
Evidently, she kills you by making you stand in a corner, then pushes you over. This is particularly effective if you happen to be a 5-year-old with brittle bone disease.
How would I win?
Given how much warning I'd have had by this time (find little stick figures in odd places, someone making a lot of noise at night, moving all my stuff around, generally being a pain in the rear. Essentially, it’s the Blair Witch saying "please leave the woods or you’ll force me to be mildly irritating for a while longer."),
The Blair Witch is, however, old, dead and picks on children. I'm plenty old enough to just punch her in the face and stroll away, possibly walking on her lawn in the process.
