Yk, I hate that adaptations keep making Peter a high schooler, and not just because it means he never evolves, but because the adaptations now also include wider Marvel, whitch usually (thanks to the MCU) is at the modern day stage with legacy characters and new age teen heroes, meaning that Peter is taking up Miles' spot and you can really tell when they put him next to someone like Kamala Khan or Sam Alexander who are Miles' pals. Tho Peter taking Miles' stuff is just a modern issue overall, just look at MCU whitch just stole and re-skinned Miles' personality, characters, story-beats, even the costume to an extent and then made it worse.

agree 👏

Just thinking about how awards shows are generally tedious affairs even under the best of circumstances, and David clearly was doing his best to get through reading a bunch of pablum on the autocue (teleprompter) unscathed, and the very first thing he does to retain some semblance of sanity and hold onto a piece of his real self in the midst of playing the part of David Tennant, Award Show Host is to take part in a bit/go right up to his emotional support pet, a.k.a., Michael. While holding an actual pet, no less...

(Also that dog is officially their child and this entire thing gave me British Birdcage vibes with David as Albert and Michael as Armand and I will not be taking arguments at this time...)

My life expectancy increases by decades whenever YinWar discuss their brand of fanservice and their boundaries on that matter. These men never mince words to remind their own fandom and media alike that whatever fanservice crumbs they drop are nothing but a performance, and that their off-camera relationship is nobody's business but theirs since they're a lot closer than they'll ever let the public see.
