I disagree, I think Death is an interesting movie (and it is a movie) in its own right.
It's unfortunate that they have omitted the real Rebirth but it wont matter to most people.
Death might sound like a ripoff as it's "just a summary" but it's much more than that really. In a way it was a "this is all the stuff you should have been paying attention to when watching eva" - and it does include interesting scenes that aren't in the normal tv version.
The problem is that Death and Rebirth isnt really designed for us - it was designed as a teaser for the final movie. That's all very well if you are in Japan in the late 90s but here and now Death and Rebirth dont really mean much to us as many of us have already seen the movie and are just waiting for it to be released.
However, I still think it's worth seeing Death but the Manga Video release isn't very good for collectors as it doesnt have the real version of Rebirth.
I love the English version of End of Evangelion especially when Shinji says that he is fucked up, that was so damn funny. Trust me End of Eva is so much better in English and I cant wait until its "officially" released. As far as death and rebirth go, its ok but I really hate re-caps.
