Review: For a first film in a proposed series it achieves the right balance. It is done with style and class showing Modesty's early days as a refugee and the start of her rise to power in the criminal world. I think it is a very honest/true portrayal of her character exactly as the writer Peter O'Donnell intended. Alexandra Staden as Modesty is stunningly beautiful and an excellent choice. She acts very convincingly as the tough survivor with an exterior of cool/intelligent/innocence. And full marks to Tarantino for choosing an unknown actress for the role - much more believeable to have a new face creating the part. I'm looking forward to the next film. Question: is it a negative review?

Ex Output:
no

Review: This is by far one of my favorite of the American Pie Spin offs mainly because in most of the others the main character (one of the young Stiflers) always seems unrealistic in nature. For example AP: The Naked Mile. You have a teenage guy surrounded by naked college chicks , and has one in particular hot on his trail to rid him of his virginity "problem" and he ends up stopping mid-deed and rides a horse back to sleep with his girlfriend, who keep in mind gave him a "guilt free pass" for the weekend. I can appreciate the romantic aspect of the whole thing but let's be realistic; most people who are watching these movies aren't particularly searching for a romantic story.Whereas the most recent installment finally seems to realize who the audience is and good old Erik Stifler seems to wake up and smell the roses and as always Mr. Levenstein lends his "perfectly natural" eyebrow humor to the equation and scored a touchdown with this new movie.

yes

Review: I first saw this as a child living in East London. The scars of Hitlers Luftwaffe were all too evident and the landscape of the movie was reminiscent of our street. I remember having nightmares after seeing it. The odd thing is, it really hasn't dated if viewed as a piece of social history in Cinema fiction. Apart from a globally destructive war, the scale of the machines was badly awry, more Nano-Technology now, but overall, an excellent and well-crafted work. It was interesting to see how space travel was perceived back then. I would think that firing a spacecraft from a gigantic gun would almost certainly kill the astronauts. However, much was right. Mans desire for war, mans inhumanity to man. The means of war as a catalyst for development. Question: is it a positive review?

Ex Output:
yes
