These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
"Funny Aneurysm" Moment: Certain ideas about the users of the Wired are eerily similar to the users of a very popular real-life imageboard.
Hell Is That Noise: Pretty much everything. After watching this, you'll never hear humming telephone lines the same way again.
Les Yay: The only two people Lain ever has any real connection to are Alice and, to a much lesser extent, Mika. Alice and Lain, however, are not related and occasionally have... shall we say, moments of intimacy that go far beyond mere friendship. Hell, Lain even tells Alice she loves her towards the end, though the circumstances imply it's agape, not eros.
"Protocol 7 is expected to allow the seamless sharing of information, information that will be shared between the Wired and the real world. And now, the following message. Let's all love Lain. [Slasher Smile] Let's all love Lain, let's all love Lain, let's all love Lain, LainLainLainLainLainLainLainLainL-l-l-l-l-l!"
Misaimed Fandom: An usual example. Producer Yasuyuki Ueda said he wanted to be interpreted differently by American and Japanese audiences. He was disappointed to find this didn't happen.
