Based on available information, 'Boots, 2025' primarily explores themes of sexual orientation and coming out for a gay male character in the military. There is no indication of transgender characters, gender identity, or gender transformation themes being present in the narrative.

The movie does not contain any action or adventure elements.

Based on the provided information, all main characters in 'Boots' are portrayed with the same gender as established in the source material, Greg Cope White's memoir 'The Pink Marine'. No character's on-screen gender differs from their canonical gender.

Cameron Cope's casting matches the source's race. Ray McAffey's original race was unspecified, and the show reimagines him as mixed-race, which does not constitute a race swap. The diverse ensemble features new characters, not established figures whose race was changed.
