I don't recall Albedo being hyped at all. He certainly isn't an anime waifu, and I don't even recall hearing about him far before the actual patch.
True he doesn't break the game like Ganyu, but he really shouldn't as a support, and he's easily one of the best supports in the game. His ability does a ton of damage, on top of a ton of defensive power for something you barely need to give much mind to. The only problem with him is any difficult content where one would actually need his ability the game is suddenly bugged to break his flower. And Mihoyo still refuses to fix it since his release.

To add on to what the others have said. The story is anime good. High production budget backing it and plenty of time to flesh out the personality of characters, which most animes can't really say they have.
Also the game is not grindy at all. The grind really only comes in if you want to max out your character's combat readiness. The only place you would really need that for is optional content. For everything else, the game is stupid easy. It has to be because they are catering to many mobile users who can't deal with complex mechanics all that well on their phone. I've tried, and it sucks.
In short, the game is locked on easy mode, but if you whale you can unlock the coveted 'very easy' mode.
