What the item description and the other reviews missed is a complete list of what you get content wise, so here goes :
The complete series, remastered from the video release.
Director's cut version of episodes 21,22,23,24.
A colour booklet.
You don't get the alternate ending contained in "End of Evangelion". So for the whole actual complete story, get this and "End of Evangelion".
And for those of you confused about the movies :
Death & Rebirth - Death is an hour long recap of the series, while Rebirth is alternate episode 25.
End of Evangelion - Alternate episodes 25 and 26 in movie format.
Revival of Evangelion - Contains Death (true 2), which is the 2nd edited version of Death, and End of Evangelion.
