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?

Ex Output:
yes

Review: This movie answers the question, how does a relationship survive when your girlfriend is codependent, clinging, needy, jealous .. and has powers and abilities far beyond those of mortal women?Without spoiling the movie, I can safely assure you it does not, but there's great fun to be had along the way. Uma Thurman is perfect as the mercurial super-heroine, an uber-babe, mysteriously named G-Girl, who unlike most in her sisterhood, is not *always* dedicated to truth, justice, and the American Way. Thurman is also believable as the thoroughly daft, yet somehow still fetching, curator Jenny. When she is dumped for a less endowed but more emotionally secure and well adjusted rival, G-Girl goes ballistic, and what follows is not pretty. It's funny, but it's not pretty ..It's a delightful premise, hell hath no fury like a super-heroine scorned, and those involved don't altogether carry it off, but it has its moments, and I think I'll get the DVD.I liked this movie .. Question: is it a positive review?

Review: This is, without a shadow of a doubt, one of the scariest and most intriguing episodes of Doctor Who.

With no other alternatives, they decide to find what lies at the bottom of the pit, an event which surpasses even The Doctor's expectations. Whilst there, the Doctor is forced to make what he considers to be the ultimate sacrifice...Meanwhile, Rose and the other members of the Planet try to find a way to fend off the Ood, whose minds have been poisoned by the Beast. Also, is Toby Zed truly cured of his possession by the Beast? Question: is it a negative review?
