I've been a huge fan of step up series since the fist movie realised. The whole thing wan't all about dancing but find your dreams-follow your dreams -make dreams come true. It's really encouraging.especailly for youngsters
 Followings are my interpretation of  the names of the Step up series:
Step up 1 (one)  = Step up won(1) the floor. The girl Nora was an incredible ballerina. She have to find a dancing partner before the school conpetition start, but no one  is good enough for her. Untill she found Tylor (a really good street dancer). Their dacing totally won the judges over and won the floor/

.

Step up 2 + step up together .In this story.Andy got kicked out form the dancing group -401. The only way can stay in Baltimore was going to school and be a ballet dancer. But she never forget that how eager she wants to compete at the streets, in order to perform there, she formed a new dancing group and got some dancing genius at BSA together. finally they win together.r.

Step up 3 (Step up thrills(three) of electric sensation). Moose got accepted by the New York Univerisity.Soon,he got to know some friends who are good at dancing streets.He join in the "Pirate". Since he majored in Electrical Engineering, he add the electric sensation in their dancing choreography.yep, their dancing speaks louder than any words.

Step up 4 =(Step up forever).In this part, dancing was no longer a competition or something else. Dancing was like kind of powerful speech make people to be heard, it was a way to express people's feelings. The Andersom Properties wanted to buy the place where the dacing team -The MOB sees as their home. They( The Mob) can't let others do anything to change the place where they live since they were born.Then, step up and dance to speak: the citizens listen.
They made a point that Entrepreneurs can't buy anything they want without even asking . Money can't buy anything. people has the right to make their voice to be heard. So Step up! 4ever!

Step up 5 to be continued.maybe step up 5(Fight your dreams or.......)
looking foward to the 5th episode .
