Bethesda fans are really huffing massive copium with the state of canon and lore right now which is insane to see, meanwhile nearly everyone who watches the show is giving it outstanding reviews jerking it off as the best adaption we've ever gotten for a video game or whatever.
I personally thought the show was watchable, I watched it from start to finish without getting bored (but perhaps it's because of personal bias to my enjoyment of the IP) unlike the Halo show and Rings of Power (both based on IPs which I love, but not nearly as much as Fallout). It was watchable, but very very stupid in nearly all departments. I thought the writing was fucking terrible, some character's decisions in the show were made with one shared brain cell in the writer's room, all main characters but especially the Ghoul had the craziest plot armor I've ever seen in my life and I'd argue was a textbook example of Gary Stu. The humor was funny at certain times but most other times some of the most cringe inducing shit I've ever seen.
Getting into lore which is an entire can of worms one small review can't get into thoroughly, all I have to say on that front is we all knew this was coming. The lore has been fucked for so long already, so this isn't anything of a surprise to those who aren't blinded by consoomerism and cope, however I think this show introduces arguably the worst and most damaging changes to the series thus far, and is fundamentally irreparable, which leads me into the case for the show's canonicity which is this -- who the fuck cares?
To any newcomers who see this, I'll say this much: Canon is such a stupid superficial blanket term. Bethesda touts this show as canon and the defacto Fallout 5 or whatever when it quite literally is irreparably lore breaking. You know why they say it's canon? Because they like fucking money and saying shit like that gets people to watch it. Nothing more. They don't give a shit for canon of their video game series and never have. Where Fallout superfans will watch this show and cry because Fallout 1 and 2 and New Vegas "canon" is broken, the show runners, writers, producers, and every other chump who excreted this are kicking their feet in the air with how much money they just made. Canon to them is the paycheck they get, not what character said what in whatever game. So if they don't have respect for what they call canon, why the fuck should you care what the giant corporation said?
I should make a thread about just this, but I'll put it here for now.
Anyway, I'd give the show a 3/10. There were things I liked, the first episode started off strong but then stumbled and didn't stop falling.
