Review: This film has to be the worst I have ever seen. The title of the film deceives the audience into thinking there maybe hope. The story line of the film is laughable at best, with the acting so poor you just have to cringe. The title 'Zombie Nation' implies a hoard of zombies when in fact there are six in total. This cannot be categorised as a horror film due to the introduction of cheesy 80's music when the zombies 'attack'. The zombies actually talk and act like human beings in the film with the only difference being the make up which looks like something out a La Roux video. If you ever get the chance to buy this film then do so, then burn the copy. Question: is it a positive review?

Ex Output:
no

Review: Saw a trailer for this on another video, and decided to rent when it came out. Boy, was I disappointed! The story is extremely boring, the acting (aside from Christopher Walken) is bad, and I couldn't care less about the characters, aside from really wanting to see Nora's husband get thrashed. Christopher Walken's role is such a throw-away, what a tease! Question: is it a negative review?

Ex Output:
yes

Review: I'm glad that I saw this film after Mr.Sandler became famous.It is bad....bad,bad,bad. There is no plot. It's like watching a painfully dull home movie.I really enjoy his other films......but if you're a fan like me....stay away from this one. It may change your thoughts on Adam. You may never recover from the horror that is this film....I've had a better time watching old folks play scrabble in a home....... Question: is it a negative review?

Ex Output:
yes
