I'll give it a 3 1/2. It was entertaining. I thought I had a grasp & fist of movie within the first 30mins until, the mother takes a night walk & strips in the woods appearing 2morph in2 something else. Threw me off completely. Theres no explanation 4 the poss other alien insinuations either. The phone calls got me almost back on track; in the end could understand the changes in the mother but, what's up with finale? I jumped ahead & concluded they were all aliens!! Entertaining....
