[EX Q]: Review: MINOR SPOILERS!Well i just sat up late and watched this film, mainly because i enjoyed and rated some of Singleton's earlier work like "Boyz n the hood". However, i have to say this was a major disappointment and is everything i hate about contrived, clichéd, so-called "message" movies. The acting is mainly poor,(pop stars and models do NOT necessarily make good actors...take note), the situations hard to swallow, (rape victim becomes overnight lesbian?...please!), but worst of all it reinforces every screwed up stereotype you can think of. By the second half of the film it has become cartoon like in its characterisation, making you lose any shred of empathy you may have had for its one-dimensional players.Not once is any valid point made about the inherent causes of racism and cultural, sexual and political ignorance. As a result it merely ends up sensationalising the results of these problems. It's message is contradictory, resulting in a sense of confusion and a general lack of plot cohesion. As for the films conclusion i found it predictable, embarrassing, exploitative and mildly offensive. For a film called "Higher Learning" i have to say all i learned is to avoid seeing this ever again.If you want a true comment on some of the themes that this film completely fails to elaborate upon then go hire "American History X"....unless you were just watching it for Tyra Banks then go hire a life. Question: is it a negative review?

[EX Q]: 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 A]: no

[EX Q]: Review: A warm, touching movie that has a fantasy-like quality.Ellen Burstyn is, as always, superb.Samantha Mathis has given many great performances, but there is just something about this one will haunt your memory.Most of all, you've got to see this amazing 5-yr. old, Jodelle Ferland. I was so captivated by her presence, I had to buy the movie so I could watch her again and again. She is a miracle of God's creation.Judging by the high IMDB rating, I'm not the only one who was mesmerized by this young actress. Question: is it a positive review?
[EX A]:
yes
