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.
Distaff Counterpart: to the film version of The Fault in Our Stars. Both have the main protagonist narrating the movie, their first loves are gone (Rosemary leaves forever, Augustus dies of cancer), both protags get their first kiss, both are love at first sight, and both are produced by 20th Century Fox. The only difference other than the gender of the narrating protags is Gabe's a child while Hazel's a teen.
Executive Meddling: The commentary track mentions that a number of scenes (including where Gabe and Rosemary get lost going to the open house) were inserted at the request of the studio executives. The same commentary track also makes it clear that this was hardly a bad thing.
And an inversion: the studio kept insisting that Gabe wear a helmet whenever he's on the scooter. Some scenes were shot as thus (and they're included in the DVD with running commentary), but eventually the directors won.
Ships That Pass in the Night: The Movie. Not strictly playing this trope straight, but this is in essence a major theme of the film. Gabe and Rosemary have only known each other well for only two to three weeks and then go their separate ways. Gabe even invokes this trope (down to the title, or very close to it) in their last scene together.
