Input: Consider Input: Review: this independent film was one of the best films at the tall grass film festival that i have ever seen there i loved it there are so many things that was great about the film on top of all that the cast and crew that i had the opportunity to meet were absolutely phenomenal.I thought that Avi did a great job in his role. and Ricky Ullman was absolutely true to his role for a Disney actor i was amazed at his talent to be able to go from cheesy teen comedy to such an adult role with no problems the talent in the film was just amazing the cinematography was just great if you want to see an independent film this is one really that you should see.I think that Mr Gruver would have been so proud to have such a submission in his festival and his parents loved the movie so much when it won the audience favorite they went and saw it again. this truly was a great film it was dark and funny and sad and truly emotional it was just fabulous. I am honestly just so enthused by this film and i really don't want to spoil it for any one just see it and truly be amazed at it i think that these film makers really have what it takes to go places and I hope to see more work from them in the future. Question: is it a negative review?

Input: Consider Input: Review: While originally reluctant to jump on the bandwagon of watching "Lost", I accidentally caught one episode at the beginning of season 1the one with the polar-bearand it has had my undivided attention ever since. The show, that is. Not the polar bear. So bear (heh) with me while I throw out as much rambling, semi-coherent praise as I can muster."Lost" takes a simple idea of a passenger flight full of people crashing onto a desert island, and gradually adds extraordinary depth to its premise by exploring each character deeply and unflinchinglywhat drives them, who are they? Where did they come from? It soon becomes clear that the island upon which they are stranded acts as a common denominator for many things in their lives, whether they're running away from something (Sawyer and Kate among others) or getting in touch with spirituality (Locke, Claire). But "Lost" also zooms in on the island itself and the mysterious horrors that it houses... and they all seem to be strangely connected.While television actors are not exactly known for their subtlety or dazzling acting abilities, most of the cast of "Lost" are, in truth, spectacular actors for their respective parts, projecting heart and humour in their performances. There's also a multitude of eyecandy, but not generally of the plastic Hollywood kind as most TV shows. The characters all feel very real and they are extremely compelling to watch. Their interactions rarely fall prey to predictable sappiness, petty arguments or cheesy melodrama (although they are annoyingly secretive)  these people are first and foremost trying to survive and whatever relationship appears is treated secondary to action. The realism of these characters facilitate an already well-sculptured plot. About this plot... Imagine a tree as the template plot, then the branches as subplots (in this case, one branch for every character)  well, Lost adds twigs to each branch and then tiny twigs to those twigs as other story lines. If you're a brother/sister to one of the main characters in the flashbacks, you will get your own storyline. If you're a DOG you will have your own storyline. Unless the writers manage to weave them all together into some glorious culmination in the end, they are setting themselves up. I am more than a little worried there will be some disappointing cop-out to this show, as I'm sure most people are.But assuming the writers do pull this off, "Lost" is possibly the best show ever to hit television.9/10 Question: is it a positive review?

Output: yes


Input: Consider Input: Review: Ashanti is a very 70s sort of film (1979, to be precise). It reminded me of The Wild Geese in a way (Richard Burton, Richard Harris and Roger Moore on a mission in Africa). It's a very good film too, and I enjoyed it a lot.David (Michael Caine) is a doctor working in Africa and is married to a beautiful Ashanti woman called Anansa (Beverley Johnson) who has trained in medicine in America and is also a doctor. While they're doctoring, one day she is snatched by slavers working for an Arabic slave trader called Suleiman (played perfectly by Peter Ustinov, of all people). The rest of the film is David trying to get her back.Michael Caine is a brilliant actor, of course, and plays a character who is very determined and prepared to do anything to get his wife back, but rather hopeless with a gun and action stuff. He's helped out first by a Englishman campaigning against the slave trade that no one acknowledges is going on (Rex Harrison!), then briefly by a helicopter pilot (William Holden), and then by an Arab called Malik (Kabir Bedi). Malik has a score to settle with Suleiman (he is very intense throughout, a very engaging character), and so rides off with David to find him and get Anansa back - this involves a wonderful scene in which David fails miserably to get on his camel.Then there's lots of adventure. There's also lots of morality-questioning. The progress of the story is a little predictable from this point, and there are a few liberties taken with plotting to move things along faster, but it's all pretty forgivable. The question is, will David get to Anansa before Peter Ustinov sells her on to Omar Sharif (yes, of course Omar Sharif is in it!)? Question: is it a positive review?


Output: yes
