PROBLEM: Review: When you go at an open air cinema under the Greek summer night you usually don't care what the movie is! Edison started really good with some good effort from the singers-who-want-to-be actors and a once again great Morgan Freeman but... (In a movie there is usually a good start to catch audience,done, a bit boring yet story filling middle of the movie that is more about characters and less about action ,done, and the third part is something really good so that you can remember the movie...) when you see 30 elite police officers (packed with weapons that can demolish a building) shoot at a guy behind a car, fail to hit him even once while he kills all (but 3) and then the guy takes out a flame thrower (to kill the rest 3) ,you realise that the Greek summer sky filled with stars is way too good to be distracted by a movie like this! Question: is it a negative review?

SOLUTION: yes

PROBLEM: Review: This film's trailer interested me enough to warrant renting the DVD. However, the resulting movie is absolutely dire! Admittedly, this is not the worst film ever made, or the worst film this year, but it came damn close!The main issue is the film not knowing what it wants to be: comedy, adult drama, thriller, teen-porn? The story is interesting, as it deals with the pitfalls of mail-order brides, but the film is a mess. What starts out as a mildly interesting "comedy" (a word I use in the loosest possible terms), then goes totally in reverse, and degenerates into a very dark and distasteful misogynistic thriller. Nicole Kidman should know better, and Ben Chaplin is wasted! As are Matthieu Kassovitz and Vincent Cassel, whom I can only presume did this for the money.This is a bad film in pretty much every single aspect. It's not funny, it's almost so sexist that you could almost forgive Benny Hill for everything he did, and the dramatic elements are just downright nasty. A film to be avoided, unless you absolutely have to see Kidman or Chaplin in every one of their films! Question: is it a positive review?

SOLUTION: no

PROBLEM: Review: As a grownup in my mid-40s, I am not even close to any of "Nancy Drew"'s key demographics, but I was pleasantly surprised by the film this afternoon; so, I could tell, were the pair of sixtyish silver-haired ladies down the row from me. The older man who left the theater just ahead of me specifically praised the film to the 20-ish female usher (who said she'd seen the film the previous evening and quite liked it).More to the point, however: In the row just ahead of me, there were nine -- count them, nine -- ten-year-old girls lined up next to each other, passing popcorn and hot dogs and candy back and forth and giggling through the previews.Once the film began, they promptly settled down to watch........and didn't so much as peep till the closing credits began to roll.This is not a perfect film; it doesn't quite pay off its high school subplots, it's not quite confident enough of its own tone, and its thugs are just a hair too far over toward critically inept at times. But the adaptation of the source material is essentially respectful, the plot hangs together fairly well, and it treads deftly between the sins of excessive cheesiness and excessive modernization. Last but not least, Emma Roberts carries the movie with startling grace -- Josh Flitter's superb timing notwithstanding, this is Roberts' movie, and she pulls it off beautifully. Her Nancy Drew is very much the direct ancestor of Kristen Bell's Veronica Mars, and the film is also a lineal descendant of Jodie Foster's early and underrated "Candleshoe".In today's marketplace, it's a rarity: a family movie that respects its viewers' intelligence. As such, it won't be to everyone's taste -- but for what it is, it is the best movie of its kind in decades. Question: is it a negative review?

SOLUTION:
no
