choosing a favorite moment is extremely hard for me because i actually went into the show knowing nothing about it, so everything was a thrill and a surprise for me.
i think what drew me in the most was actually just the scene of charlie and nick texting each other at the beginning of episode 2. i know it's such a small thing, but it's the only time i have ever seen a tv show get the way that young people communicate completely right. like the detail that went into *how* they type, and the getting frustrated and tossing your phone across the room. and nick pulling the "i'm your friend and i do care" to get charlie to open up and charlie baiting with the "supportive straight friend" stuff... and at the end of the episode where nick zooms in on the picture with charlie and gently strokes the side of his phone... all of that was SO REAL to me like i have experienced all of that. so even though that's not like one of the big moments that everyone talks about, i think the attention to details in moments like that were what really made the show feel so impactful to me.
as for best page-to-screen moment... like i mentioned! i didn't know the comics existed before watching, so i actually read the comics right after finishing the show (like immediately after) and i was so shocked at how faithful the adaptation actually was!
i feel like it's gotta be the first kiss and its aftermath tho... like the kiss was done exceptionally well, and so was the rain scene, and nick and charlie apologizing to each other in charlie's bedroom? all of that was just stunning!
but i also REALLY LOVE the way they adapted nick and charlie talking at the bowling alley... like the way that there were obvious changes made (instead of being at the table, they were in front of the claw machines) but they still kept the same conversation and the same energy. i love the frame in the comic where nick is saying "i wish i had met you when i was younger" and he lays his head down on the table, so charlie does the same... and how in the show for that moment they had nick and charlie lean their heads against the claw machine in the exact same way... like that was so subtle and so well done and it impresses me every time i think about those little details taken from the comics that wouldn't have even been necessary to include, but enhance the experience of the show so so much.
