I would like to give my sincerity:
it shocked me for all 117 minutes, it is full of characterizing references that are very much about the main protagonist Charlie (I add that it is great Oscar deserved performance by Brendan Fraser great actor 💯 )
Also, the quote from Melville's Moby Dick (there are references in the film as well) that I would like to add is also my absolute favorite that somehow encapsulates:
"My body is but the dregs of my better being."
