No clarification. The ending of both the series and the movie were like Kafka's the Trial: the come out of no-where, suggesting that there's meaning to be found, but ultimately conclude nothing. We're left on a beach with Asuka strangled-and-yet-not-dead, Shinji crying softly, a vision of Rei appearing randomly over the Sea of LCL, and the wonderful cockslap last words of "I feel sick." HWHAAA? Thank God for Wikipedia & eva-geeks.org; otherwise I'd be adrift.

Not enough clarification on universe mechanics. Specifically, the workings of souls, AT Fields, Angels, Seeds of Life, the Dead Sea Scrolls, and even humans.

The religious symbolism being kind of hammered in wherever it fits, even when it makes little to no sense.

Lots and lots about what's bad in humanity, but very little ideas of how to fix anything.

Psychologically rich, but Philosophically bankrupt.

The awkward English voice acting during the earliest episodes of the series.

The writers did such a perfect job of making Gendo a despicable bastard that he's absolutely unnerving to watch at points, always commanding NERV to do callous, insane shit, then sitting back and watching in his typical stone cold pose. Sure, he only does what he must to save the world, but I still want to jump into the TV screen and punch him, especially in Episode 18.
