"Cirque du Freak: The Vampire's Assistant" is a strange but pleasant movie. What do you want from a movie based on "horror" novels targeted at 12 year olds?
"Where the Wild Things Are" is good, but strange, and so very NOT a children's movie, unless you are taking someone else's children, and you don't like the parents much. The movie explores abandonment and frustration and irrational behavior without resolving anything, which is likely to mess with pointy little heads quite a bit.
"Saw VI" is a moderately clever morality tale drenched in gallons of blood. Which is to day, it is very much of a piece with all of the other "Saw" movies.
"Astro Boy" is about three parts "Pinocchio", two parts after school special, and one part "King Kong". I liked it; Dementia refused to watch it (I have no idea why).
"Paranormal Activity" is a clever movie that, while deeply flawed, demonstrates just how scary a movie with a mediocre script and no budget whatsoever can be (pretty damned scary, actually). It certainly blows every other "camera within the narrative" film ever made out of the water. On the other hand, the male lead is probably the single stupidest character in the history of horror films.
"Stepfather" is a pretty decent thriller. The story is badly out of date (you CAN NOT exist at that level of affluence for any length of time without a Social Security number in post-9\11 USA), but works well enough once you swallow that. I was amused at the pains the script took to separate characters from the cell phones as the climax approached; functional cell phones are writer's nightmares. Also, several minutes of Amber Heard wandering around in a bikini don't hurt. (Cheesecake won't make or break a movie, but it will certainly sweeten a movie about which I am vaguely positive...)
