Review: It is a great movie if you have ever named your cars or are really into old, fast, or exotic cars. It has a plot and a lot of action. The car scenes are great except for the totally fake car jump scene. All of the other scenes are great. I really enjoyed it and I hope everyone else does as well. Question: is it a positive review?

Ex Output:
yes

Review: For starters, I didn't even know about this show since a year or so because of the internet. I have not once seen it on TV before in my country, and a lot of people do not usually know about this show. It is a pity though, because this is easily the most original and clever animation I have witnessed in years.I don't hand out 10 points a lot, but this is one show that truly deserves all 10 points. Even though at first glance this might seem like a typical cartoon but keep in mind that this is not a kids-show though. When the complete story unfolds itself, you know that this is a real deep storyline, with a spiritual message. This spiritual part of the story is largely based off spirit-animals, a old Indian believe that has been preserved for many years. This gives the show a original twist that you can't often find in animated shows.The overall design is also something very different. At times it resembles Spawn a bit in terms of gritty design, and other times it takes on a more cartoony approach. I believe David Feiss who also created and directed Cow and Chicken animated a segment in the show (as he also drew that segment in the comic).If you are looking for a mind-twisting show, a show that takes on various subjects such as reality, suicide, spirituality, life, then this is something you should not miss. Once you begin watching, you are probably going to watch it to the end. One minor fact may be that the show takes on less material from the comic, but this is not too annoying. The only question remains though, where is the DVD?! Question: is it a negative review?

Ex Output:
no

Review: Like last year, I didn't manage to sit through the whole thing. Okay, so Chris Rock as a host was a good choice because he was vaguely engaging. Or rather, out of all the total bores packed into the theatre, he at least wasn't in the Top 10 Most Boring. A lot of the presenters, on the other hand, were in this coveted Top 10. I hadn't known that the whole thing had been done by autocue (although I knew it was scripted) but it was really terrible to see these supposedly good actors unable to insert expression, look away from the cue and stumble over simple words (Natalie Portmanif there's no director, she's gone). The Night of Fancy Dresses and Boring Speeches was long and tedious, Beyonce Knowles butchered some good songs and there were very few decent acceptance speeches and clips. Adam Sandler wins the Worst Presenter award.For helping me write this review I'd like to thank my Mum, my Dad, my lawyers and my pedicurist for all believing in me, and I'd like to point out that I have a high metabolism and of course I haven't been starving myself for a month. I'm not going to cry...thank you. Question: is it a positive review?

no
