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.
Idiot Plot: See the page. There are so many things that could've resolved this (rather overlong) plot in a few minutes.

Why Would Anyone Take Him Back?: Subverted, in that she doesn't. But seriously, why would Rae even waste time being polite to Adam? He left her for frogs! Yes, frogs.
