This show was the seconed anime i watched (first was eva) and i gotta agree with you. Its very slow, very boring and too minimalistic to be enjoyable. I have to admit the show does have "complex" ideas and symbolism but its just not fun to watch, unlike Evangelion. So yea i find it to be boring too despite it sophistication. On another note Lain being autistic and a shut in makes her apealing to autistic men and attention seeking whores as well as troons.
