Ending Fatigue: The police shootout. The assassination has already been thwarted, and even Betty still being in danger can't add much to the excitement of a bunch of faceless nobody cops trading shots with the bad guys for ten whole minutes.
Harsher in Hindsight: Ramon falling to his death after getting shot by Jill. Frank Vosper, who played Ramon, died three years later after falling off the deck of an ocean liner (officially ruled an accident, but rumored to be a suicide).
And You Thought It Would Fail: "Qué Será, Será" again, big time. Doris Day initially was extremely reluctant to even record the song, calling it "forgettable children's song". It went on to win Oscar for the Best Original Song, ran second on US Billboard chart and first on UK Singles Chart and, ironically, ended up as a theme song for Doris' own The Doris Day Show. It is now #48 on AFI's 100 Years 100 Songs list.
Even Better Sequel: A lot of people consider the remake to be even better than the well-received 1934 original. Alfred Hitchcock at the very least felt it was more polished.
Narm: "How are you going to get the child out of here? EH!? EH!? EH!?"
She Really Can Act: Viewers who only know Doris Day from old-fashioned pop music and romantic comedies might feel pleasantly surprised by her dramatic potential in this movie, especially after her character receives word of Hank's kidnapping.
Tear Jerker: The scene in the 1956 film where Jo learns about her son's kidnapping is wrenching. As listed above, Doris Day does an excellent job of acting the character's fear for her son's safety, her anger that her husband sedated her, and her confusion brought along by the pills.
What an Idiot!: Some might wonder why Ben needs Jo's help to realize "Ambrose Chapel" refers to a church instead of a taxidermist. The subtitles on the Blu-Ray make this seem especially idiotic by spelling Bernard's dying words without the extra L. In Ben's defence, though, we do get a look at Bernard's actual note, and it had the word misspelled as "Chappell".
