PROBLEM: 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?

SOLUTION: no

PROBLEM: Review: I have never commented on a film before. I watched this movie with my girlfriend last night. I've read comments saying this movie stays with you. It does. It's been almost 24 hours and I am still completely affected. This movie left me questioning my own self. How can I possibly compare myself to a character such as Ben who is totally selfless. I loved this movie. I love movies that keep me guessing and wondering until the end. I feel two emotions predominantly, happiness and sadness. An amazing feel good movie and a very sad one too. I so wanted Ben and Emily to be together, but in the end, they were, forever. If you haven't seen this movie, get it and watch it. Just make sure you have no distractions. You'll want to see every nuance in this picture. One for my library. Question: is it a negative review?

SOLUTION: no

PROBLEM: Review: I loved the idea of this film from the moment I first saw a trailer for it. Einstein has always been one of my heroes and the image of him as the kindly, playful, slightly mad genius was enough to get me to see the film. The added spice of Matthau as Einstein made it even better.The story is pure fantasy, but a delightful one. An auto mechanic falls in love with a beautiful woman, who happens to be Einstein's niece. With the help of four Fairy Godfathers of Physics, Ed embarks on a quest to win Catherine's heart. Throw a jealous fiancé (who exemplifies the worst of experimental psychology) and Eisenhower into the mix, and you have pure fun.The film is filled with great character actors and delightfully sweet and daffy performances. Walter Matthau play Einstein as a mischievous imp; cupid with a slide rule. Tim Robbins is wonderfully endearing as Ed and Meg Ryan plays a step above her normal rom-com level. Stephen fry is a joy as the "RRRatman" and Ryan's fiancé; who lacks a single romantic bone in his body.The film fell below most radars, but is a delightful treasure that does not grow stale with repeated viewings. It features first-rate writing and performances and is a gentle treat in a less than gentle world. Question: is it a positive review?
