VERDICT: Passing grade (maybe 2.8 stars, rounded up). Starts off well, with a sympathetic insomniac protagonist in a serious situation.

NOTES (may contain mild spoilers):

Spoiler

PROS:
++ Some of the descriptions of sleepless symptoms were good. Sleep deficit sucks!
++ Some good "Who can I trust?" plot stuff.
++ The mother was sometimes funny ("It's a cult!").
++ Does not end on a cliffhanger.

If the danger and intrigue were ramped up 20% and the characters were quicker on the mental draw, this would actually make a pretty good movie.
