Dear Anastasia;
First thing, here is a link to the New World Translation on line.
http://www.watchtower.org/e/bible/index.htm
Read it yourself, check some favorite verses and see how it renders the text. You will find it to be a very clear reading modern English Bible. As for accuracy the New World Translation is a very accurate translation. Here is a link to a site where it is shown, that according to a testing system designed by a well known Bible scholar, the NWT NT translation is one of the best out of the 55 translations considered.

The internet attacks on the NWT is just part of the overall attack on all things Jehovah's Witnesses. If the NWT had been published by some minor publishing house, the attacks on the NWT probably would never have been made, they don't bother to attack the other translations that use very simular renderings in some of the same verses they argue over. The rendering used by the NWT in many of the disputed verses are discussed here at this link with the reasons why the rendering used is closer to the biblical text.

The NWT has many advantages because of the consistency in the way the translation was done, here is a link that goes into some of them.
Advantages of the New World Translation
Personally I love the NWT, I find it to be an absolutely wonderful translation. I have used it a lot in scriptural discussions and it really is a great translation for really getting to understand the Word of God.
