I absolutely loved You Got Served. I'll admit, you aren't into dancing and music, this probably isn't the right movie for you. However, if you love dancing and you are a fan of good music, you will love this movie. You Got Served contains some of the best dancing you will ever witness. It is amazing. I won't go into details about the dancing because you have to see it to believe it.
As far as the acting, I think the members of B2K did a great job, especially since this was their first movie. The most impressive actor of the bunch was definitely Jarell Houston, aka J-Boog of B2K. There is one particular scene in this movie where his acting skill are absolutely phenomenal. He makes the viewers actually feel what he is going through. Marques Houston, who is also an incredible actor (if you haven't got his debut solo album, MH, go get it! It is amazing!), does a fantastic job portraying the character of Elgin.
The plot of YGS is not as bad as the critics say it is. You will enjoy it if your mind is open to it. I recommend this movie to anyone who likes to be kept on the edge of his/her seat and would like to witness some unbelievable dancing. Even if you were not a fan of B2K, or aren't a fan of Marques Houston, there is still a chance that you'll enjoy this movie. If anything, go see this movie for the dancing. Even top-notch critiques can't argue with that...they have all said the dancing was amazing.
