10 Horror Movies You Didn't Realise Stupidly Broke Their Own Rules
7. The Xenos Are Weak Against Light... But Attack In Broad Daylight - Alone In The Dark
The Rule
Uwe Boll admittedly isn't a filmmaker who seems to care much about internal consistency, but even so, his 2005 video game adaptation Alone in the Dark explains half-way through that the CGI beasties known as the Xenos are weak to sunlight.
One of Edward Carnby's (Christian Slater) associates literally tells him, "They live almost exclusively in the dark. Sunlight is lethal in large doses."
The Breaker
Though the film sticks to this rule until the end, the very final shot is a sequel-baiting jump scare in which Carnby and archaeologist Aline Cedrac (a howlingly miscast Tara Reid) are implied to be attacked by a Xeno.
The scene takes place in broad daylight and so would certainly cause considerable harm to the creature, and yet, the thing still manages to haul ass in their direction with extreme purpose. What gives, Uwe?
Then again, most viewers probably never noticed this plot hole because they were mentally checked-out long before the ending even arrived.
