They are well worth watching too, but you need to be aware of the context to fully appreciate the message.

The sequels that stop tracking so close to the original is where it takes off. I still prefer the original but it didn't feel like a simple re-make at that point.
It was entirely technobabble and metaphysical nonsense with no character development.
I agree that the CGI scenes where kind of weaker than the old animated fights.
The 4th brings it back somewhat, but ultimately the finale is still the typical Eva "here's a bunch of religious babble half-explaining what happens overlaid with crazy imagery" which imho had its last hurrah in EoE.
