why is there no streaming for Evangelion?
i usually will only watch something once, so i dont have the money to buy dvds like this.
Which version of Evangelion do you mean: the Rebuild films, or the TV series?
In the case of the Rebuild films, it's licensing issues. Movies are far more rare than shows to be available for streaming online.
In the case of the TV series, no one owns the rights to it anymore in North America (thanks, Gainax -_-).
Gainax doesn't own Eva anymore. The license was given to Khara.
Plus, a Blu-Ray box set is coming in Japan later this year.
