Are their actually any good comic book youtubers to follow that actually focus on the release quality of physical editions and discussion of the comics themselves? Don't care about investing or #comicsgate drama channels, just looking for some chill.
Very, very few. Most comic book related youtubers are wiki and plot summarizers. Another common alternative are comic book hauls and manchildren reacting to comics and endlessly speculating, like ComicPop.
Some decent channels are:
Alpha Rookie - people running it own a comic book store, and channel is on a hiatus. They mainly cover films, but venture into comics too. They go for more niche stuff that's good and will introduce you to books you might not have heard of otherwise. Sadly, they do not have too many videos.
Comic Tropes - only large comic book youtube channel that I would consider decent. Currently the tropes thing has nothing to do with channel's content, as he stopped leaning heavily on trope discussion couple years ago. His reviews/retrospectives are a bit heavy on plot summaries, but unlike most other channels he goes beyond that. Things like creator's history, circumstances behind comics' creation, and so on get covered too. Some videos discuss specific creators, trends within industry, interviews with people, and niche comic books get covered too. He even managed to talk about things like Cerebus without falling apart or ranting, even though Sim is the polar opposite of guys's politics.
Strange Brain Parts - video essays on comics. Pretty good if a bit pretentious. Guy running the channel has a thing for early 2000s and late 90s indie and niche stuff, and for Vertigo titles, but he does not cover these exclusively. Pretty good about not sperging out about comics that might go against his sensibilities. Only time I have seen him get pissy, was Q&A video when a question about current state of comics industry, creators, and quality appeared. This was at the peak of comics gate, so he assumed one of supporters was asking the question.
Earl Gray - what if YaBoi was a German guy with a large and varied comics collection. He flips through books and talks about them a bit. Very large variety of stuff covered, and he tends to be more knowledgeable than Rich too. Good source to find interesting niche and foreign books. His tastes are a bit of a mixed bag, however.
I am sure there are more, but I can't think of anything else at the moment.
Since people mentioned Ennis, the one thing I find hilarious that the irish bastard gets all hung up on and upset about is Captain America. An American super hero. If he's going to complain about "durr it's offensive to ww2 veterans" maybe he should complain about Captain Britain instead? Funny enough, those claims of him being offensive fell flat because, you know; actual US Army members read that shit. Jack Kirby, who was one of the two men who created him and drew him, actually served in WWII. Yeah, "well researched in military history" my ass. What a dumb Mick.
Ennis is a borderline "Hail Britain!" nut, and he is obsessed with SAS especially. Glorifying any foreign military rubs him the wrong way, as it supposedly takes away from royal forces' glory. These people tend to have inferiority complex towards American military, probably because British heavily depended on the U.S. in WW2 and Americans were the dominant military ever since. People like him get angry when you point out that during WW2 Polish and French resistances had to hand Britain enigma and intelligence, and that it was actually Americans and Russians who sealed the deal.
That's their target. They want that weeb crowd and they can't actually get real Japan stuff. So they make home-brew stuff and that imitates it. They've tried it on and off now for about thirty years.
Anime/Manga is on the block. They just have the problem that the Japanese don't want foreigners mucking in their stuff.
Eh, they think it looks cool. That and Frank's been canonically a Marine and a Cop. They like that. Semper Fie and all that.
No doubt. They have somewhat of a hold in videogames and anime industry through localization companies. Scanlating comics is far less work and resource intensive, so it is tougher to maintain a grip on manga. Still, few years ago there was that Attack on Titan anthology made in the U.S. It was full of typical pandering and idiocy.
