Ex Input:
An exellent study of the German Airforce from the fall of Sevastopol in the Crimea to its failure at Stalingrad. Very well written, with a clear analysis of the events. Well worth the money and it belongs in every major collection on World War II's Eastern Front.

Ex Output:
Positive

Here are the rules: 1) Every time a character says or does something that's supposed to be funny but comes off completely lame instead-take a swig. 2) Every time the movie veers off into some completely random direction that has absolutely nothing what-so-ever to do with anything, take a swig. 3) Every time a transformer does a somersault or twist in the air in slow motion before attacking-take a swig. Follow these simple rules and you'll be bombed 15 minutes in. Seriously. While watching this movie I kept thinking how many millions of dollars were spent to provide us with idiotic jokes about red coffee cups in yellow rooms and effeminate assistants with Russian accents. Every time I see one of these movies, it saddens me. Given the insane visuals-tight, more serious stories could have really made this series into something amazing. Unfortunately that's not the case. At least there's no leg humping in this one. That's something I guess...

Ex Output:
Negative


Ex Input:
Dark Side of the Moon makes the first Transformers movie look like Citizen Kane. I got about halfway through this movie before I had to stop watching. The plot was utterly nonsensical. I had no sympathy for any of the characters--the sooner Megatron kills Shia LeBoeuf the better--in my opinion. The action scenes were so convoluted, I couldn't even tell what was supposed to be happening nine times out of ten. PLEASE PLEASE PLEASE, Michael Bay, Don't make another Transformers Movie.
