Reasons Why This Sucked - SPOILERS

There must be a hundred reasons why this was such a terrible movie but a couple of amateur mistakes stuck in my memory. Here's two:

1. When the psycho nanny walks into the bathroom and strangles the father with an electrical cord, it only takes about a few seconds for him to completely pass out.

2. When the father wakes up after being strangled unconscious, he looks into the bath where his wife is lying dead (after being electrocuted). The shot lingers for about 5 seconds and we can see the top of her head and the corner of her eye. The dead wife blinks. Twice.
