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.
Hollywood Pudgy: Regarding Alex: While many fans praised the use of a relatively average body type in a gay cast, other fans had a completely different perception and considered him morbidly obese. Also, including a character of thicker build for diversity loses its effect when the entire rest of the cast is muscular and perfectly toned.
Marty Stu: Guy borders on this until you learn his true motivations...
Real Men Have Curves: Alex believes this all the way regarding himself, and professes himself as the most "real" one of the group. He even says a variation on the line itself in one episode.
