PROBLEM: Review: I watched this movie last week sometime and had the biggest laugh i've had in a long while. The plot of the film is pretty dumb and convoluted in a badly crafted way. The only plus to be found anywhere in the film are Corey Savier's impressive abs. Alexandra Paul (i think that's her name) is horrendous as the preacher's wife who has a history of depression. Ted McKenzie is gross and his character's a twit on top of it all. And as if the fact that you think she's having sex with her son isn't enough, they throw in needless sax solos at every opportunity! The end and climax of this film is absolutely abysmal and also laughable. I mean who the hell wants to carry the child of a con who tried to make you think he was your son and that you were having an incestuous relationship with him! Question: is it a positive review?

SOLUTION: no

PROBLEM: Review: I saw "The Grudge" yesterday, and wow... I was really scared, a good thing. I love horror-movies, and I really liked this one. There were so many 'surprise'-scenes (what's the English word?) that made you jump in your seat. Though, too much screaming from the audience made it difficult not to laugh. I think the most scary scene was... on the bus, when the face flashes by on the window, or when Yoko's walking without her chin. The make-up is also VERY good. Sometimes you could really see it was there, but it was still adding a freaky look to the scene. The boy was very good indeed, so cute without make-up and so terribly scary with it on. The next time I hear a cracking noise I will probably feel pretty scared... Question: is it a positive review?

SOLUTION: yes

PROBLEM: Review: I am stunned to discover the amount of fans this show has. Haven't said that Friends was, at best an 'average' sitcom, and not as great as others have made out. Let's face it, if it wasn't for the casting of Courtney Cox Arquette, David Schwimmer, Matthew Perry, Lisa Kudrow, Jennifer Aniston and Matt Le Blanc, then who knows whether this show would've lasted as long as it has done. I very much doubt that. Although as the series progressed, Friends got more progressively predictable, lame and boring that I couldn't care less about the characters- of whom are the most overrated in TV history- or of their plight, nor of who was sleeping with whom. And it went from being funny in the first four seasons to occasionally funny. And even when it had all these A-list Hollywood actors from the movie world, I still didn't bother to tune in. The writing in Friends became stale that I lost interest in this show from the sixth season onwards and as for the ending, well it was predictable to say the least.What was annoying though was that this lasted for ten seasons, whilst some of my favourite shows lasted for only three, four seasons for instance and were eventually cancelled and taken off the air for good. The show should've came to an immediate halt by the time the cast wanted bigger salaries. In truth, as much as the series waned, it was the show that was bigger than the actors themselves, not the other way round. When it ended in 2004, I was so relieved to see the back of this sitcom. Now, there is talk of a friends reunion show coming to our TV screens very soon. And yet, I for one will not be looking forward to it whatsoever. Question: is it a negative review?

SOLUTION:
yes
