PROBLEM: Review: From the blocky digitised footage to the acting that makes Keanu "I'm so wooden I could be a Plank me" Reeves look like an Oscar winner this film bites (pun not intended). The best thing about it is the box of eRATicate in the 2nd segment (which out of the three seemed to be the strongest piece in terms of storyline and 'twist'). Wish I'd spent the £3.99 it cost me on something else, like erm.... Natural Born Killers: Directors Cut. If you do buy this, you're really in for a disappointment, do yourself a favour and avoid it like the plague. If you're looking for something amateurish and with actors that are more wooden than a 2x4 then go ahead. However if you want some quality werewolf action look elsewhere, like Dog Soldiers, Wolfen, Romasanta:The werewolf Hunt. Question: is it a negative review?

SOLUTION: yes

PROBLEM: Review: Darkly comic serendipity about a cosmetics saleswoman, with odd ties to Elvis Presley, running into a sea of Elvis impersonators while speaking at conventions in Nevada...and accidentally killing each one of them through little fault of her own. Kim Basinger, a still-attractive actress of considerable merit, likes to pick quirky movies to play in, but this dreadful screenplay (by Mitchell Ganem and Adam-Michael Garber) hasn't an iota of good humor. The stereotypes and low-ball gags are not meant to be the stuff of classic comedy, but even on a shambling, shameful level, the picture is crude and sloppy. If you do watch, see if you can count how much extraneous shots there are of Basinger behind the wheel of her pink Cadillac, hands always in the same position and a non-plussed look on her face. Hopefully both she and Elvis were well paid. NO STARS from **** Question: is it a positive review?

SOLUTION: no

PROBLEM: Review: When I rented this movie to watch it, I knew that it was not going to be a mindbender movie. Instead I thought of it as a disbelief of reality where someone is going to get a serious beating. And you know what it worked. Kurt Russel did what I though was a remarkable role in showing the emotionless soldier that he was. I recommend this movie if your out with the boys and want to watch a good action film. Question: is it a positive review?

SOLUTION:
yes
