Ex Input:
Understanding Cuba! . An excellent account of how cubans escaped communist Cuba in 1994 building rafts and sailing across to their dream of America.  It follows the lives for 5 people who made the crossing. The film follows their struggle on arriving in America and looks at their lives 6 years on.   This is a True Story which is still happening today.  The film is in Spanish but there are subtitles.  Get the hankies ready!

Ex Output:
POS

Excellent . Continuing the high standard set by the quality of episodes from the third season, season 4 of Star Trek: The Next Generation maintains a high standard throughout. The conclusion of the previous season's cliff-hanger "The Best of Both Worlds" does not disappoint, it's the rollercoaster finish we were all hoping for. It doesn't end there though, the writers were brave enough to not have the next episode be "back to normal" as Star Trek is so good at doing but write a real character episode "Family" mainly dealing with Picard's trauma after being assimilated by the Borg.  There aren't any terrible episodes this season, Qpid is a bit silly with the crew as Robin Hood characters - most of the stories are strong. "Future Imperfect" continues the brinkmanship between the Federation and the Romulans (with Andreas Katsulas of Babylon 5 fame and Riker telling Picard to "shut up"), "Data's day" is an entire episode from Data's perspective, "The Wounded" introduces us to the Cardassians, "First Contact" is what Star Trek's all about, then we get into "The Mind's Eye" and "Redemption" where the Romulan, Klingon and Federation triangle plot finally starts to come out.

Starts well, comes crashing down . In the early going, I thought the choice was between four and five stars.  As the movie progressed, my rating dropped to somewhere between three and four, so clearly the first half of the movie is better than the second.  The ending was so disappointing that I had to drop my rating to two stars.    It is about a Polish man in France who marries a French girl but is divorced by her because he is unable to make love to her.    He returns to Poland without her, manages to get rich, and comes up with a plot to get revenge on his beloved Dominique.  The problem with this writing is that he loves her, so why is he plotting revenge against her?  It is senseless.    The ending is utterly surreal.  She should hate him for what he has done to her, but she is smiling to him.  He is looking at her and crying.  He has betrayed her in a cruel way.  He doesn't have the right to be crying for her.  That is like Hitler crying for the Jews.  He is still in a position to help her out, but he won't.  It's really pretty sickening.    The story becomes unclear enough as it is, without adding some fantasy scenes or memories about a wedding and a kiss.  It left me angrily saying "What the hell is going on?"  I really hate it when a director becomes unclear and plays with the audience.  I don't find that cute at all.  Tell the damn story and tell it clearly.  Besides, the ending sucks
