PROBLEM: Review: Let me first state that while I have viewed every episode of StarTrek at least twice, I do not consider myself a Trekker or Trekkie. Those are people who live in their parents basement and attend conventions wearing costumes with pointed rubber ears. I gave this movie a seven casting aside the fiction historical errors. The acting was better than average, but the plot held no surprises. They tried very hard to reverse engineer the technology but still the special effects were just to great a temptation. Now as to the historical errors, if you call them that, the first Capitan to pilot the Enterprise was Commander April, then Capt. Pike, Jim Kirk, etc.. According to a statement made by both Riker and Kirk we dicovered the Klingons and educated them and gave them the technology (that's the reason a prime directive was created) but like I said these are no reason to discredit this fine series. I hope the plots will get deeper, and then special effects can take a backseat. Question: is it a positive review?

SOLUTION: yes

PROBLEM: Review: If you're at all interested in pirates, pirate movies, New Orleans/early 19th century American history, or Yul Brynner, see this film for yourself and make up your own mind about it. Don't be put off by various lacklustre reviews. My reaction to it was that it is entertaining, well acted (for the most part), has some very witty dialogue, and that it does an excellent job of portraying the charm, appeal and legendary fascination of the privateer Jean Lafitte. While not all the events in the film are historically accurate (can you show me any historical film that succeeds in this?), I feel the film is accurate in its treatment of the role Lafitte played in New Orleans' history, and the love-hate relationship between the "respectable" citizens of New Orleans and this outlaw who was one of the city's favorite sons. Don't worry about what the film doesn't do, but watch it for what it does do, i.e., for its study of one of New Orleans', and America's, most intriguing historical figures. Question: is it a positive review?

SOLUTION: yes

PROBLEM: Review: This was a great movie with a good story. My children (10, 7, 5, and 4) all loved this movie, including myself. The music was also fantastic. No, the horses do not talk, but instead, the story is told by Spirit. And to hear a story told by a horse's point if view was fun.I think the title says it all, "spirit". This movie really gives you a sense of family and home and friends. I would have to say my 4 year old boy and 5 year old girl were really touched by this movie, and even got so into it, they laughed so hard, and they cheered for spirit in the end. Enjoy "Spirit" with your family and have your spirit lifted with this heartwarming story. Your kids will love it. I think you will too. Question: is it a negative review?
