(I'll do a spoilery review later.) Saw this last night at the De Lux over to Holtsville. I enjoyed it a lot. I was a little concerned when I heard that Hideaki Anno was going to direct it - he's brilliant, but a little bit screwy, and I was afraid that he would put a lot of NGE type weirdness into it, but, while there were some Anno-esque touches to it, I felt that he made a good G-Film, maintaining the spirit of the previous films while trying something a little new. Well worth a view if you get the chance.
I've had the DVD since Saturday, and due to bad planning, I have yet to sit down and watch it all the way through. What I have seen of it, and what I remember seeing in the theater: Yes, it it worth buying. Not a perfect movie, but worth a look,
We got ours from Amazon yesterday. We plan to watch it Friday.
