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.
YMMV: Nodame Cantabile
Ass Pull: The resolution of Rui's storyline in the anime. Trust me, you're better off knowing.
Crowning Moment of Heartwarming - So, so many, but the hug from the back at the end of the first anime and live action really takes the cake.
Another notable moment is when Chiaki crawls into Nodame's room sincerely apologizing that he missed her recital...and Nodame accepts it as he drifts to sleep on her lap drunk.
Not to mention episode 11, the entire first half of which consists of Chiaki and the A orchestra playing the hell out of Rachmaninoff.
Can we just give the whole series this and call it?
Dude, Not Funny! - Chiaki frequently uses physical violence against Nodame, played for laughs in the manner of a Boke and Tsukkomi Routine. In the live-action version especially, however, it comes across as less slapstick and a bit more disturbing...
Which is an interesting study in Double Standard since female tsunderes doing the exact same thing to male anime characters who act like Nodame for Rule of Funny are given a pass.
The Domestic Abuse trope had an entry about this, which dripped with misandry and Chiaki hate as well as Nodame Sue-fication. Phew, thank God it went away.
In one of the Paris-Hen episodes, Nodame even admits to playing up the Boke and Tsukkomi Routine simply because Chiaki's such a perfectStraight Man. Chiaki, needless to say, is not amused by this revelation.
And in another Paris-Hen episode, Nodame herselfbecomes extremely violent against Chiaki. Sure, it's played for drama, but did she really need to kick him in the head?
