I really did enjoy each of these series but I adored Serial Experiments Lain.

Romeo x Juliet is awesome.

^I actually prefer it over the literal play.

^ Same.

I also liked Serial Experiments Lain & Sekai Ichi Hatsukoi.

^Sekai Ichi Hataukoi is my favorite yaoi anime. :)

I haven't seen any of these, but I've heard of most of them.

Lain is really epic!

But there is no competing with Amnesia for me! Kept me on edge every week!
Every time she jumped i would be like "Who is it this time who is it this time who is it this time?!?!"
Not many series do that for me!

Katherine1517- Oh this anime is soooo much better than the original play lol at least in my opinion.

@CandyforniaGurl- You should try watching some of them. :)

@CrescentMoon777- Lain is pretty epic. I really did enjoy AMNESIA because, like you, it did keep me On the edge of my seat guessing. ^.^

@Alchemistlover- Haha, I agree. It made me like every character unlike the original play. I hated Tybalt but in the anime, he was my third favorite character (2nd was Juliet and 1st was William Shakespeare ;p).

Sekai Ichi Hatsukoi!!!! One of my favorites. <33 Romeo x Juliet is amazing as well, 100 times better then the play, I hate the play. Adore Amnesia too, love it.

^Haha, SIH is in my top thirty anime. :) RomeoXJuliet is pretty amazing and I agree, I prefer it over the play as well. AMNESIA was really good as well, I got a little teary eyed in the end though. ^^;

Katherine1517- oh how i wish we could have watched this anime last year in English instead of reading the play XD that'd be awesome....but i'd have a fangirl attack in school which wouldn't be good lol.
