What do you mean by again and again? Rebuild is the first true remake (?) of the Evangelion story. It may actually be a sequel though. It also has a different story and ending.

Death and Rebirth are basically clips of the series plus some new scenes. End is an alternate ending to the story. And these two were shown way back in 97.
