The answers are very few, and probably not. Only a very specific audience will be able to overlook the serious flaws of Okaasan.
Story: 1/10
The story of Okaasan starts out as standard Isekai fare, but quickly devolves into a strange, contrived-even-for-Isekai mess. Many of the problems Masato and party face should have been nuked at the dev level. What are the devs of Okaasan Online doing, letting this conga line of deranged griefers do as they please, quite literally threatening to break the game for everyone else? It’s baffling that they lack any sense of PR and any sense of protecting their own assets.
The intra-party conflict moments are marginally better, but still rely on unrealistic and nonsensical anime logic to create and solve problems. Absence of internal logic is a running theme in this anime.
Art: 4/10
Not much to say about the art of Okaasan. It’s standard fare for low budget animations. It isn’t particularly offensive in any way, and that makes it one of the best parts of the show. The designs are nothing special, but they’re nice to look at in a vacuum, when the characters aren’t making you want to smack your head against the wall.
Sound: 5/10
Again, not much to say. The opening and ending are not stellar, but they are mildly catchy. Insert tracks fit well enough with their scenes as to not be a bother.
Character: 1/10
This is another category where Okaasan utterly fails. Unfortunately, the characters of Okaasan are less characters as much as they are a loose collection of tropes from better characters, written with the consistency one might expect if a different schoolchild were assigned to each episode, were given a loose character outline, and asked to write a story. Mamako herself is the worst offender in this sense, her poor self-awareness varying wildly from episode to episode, from bad, to lethal, to just plain stupid, to even stupider yet. But, every character suffers from this lack of consistency to some degree.
Worse yet is the utter unlikability of what little consistent traits there are. You’ll want to smack Masato for being a whiny prick to his mother and everyone else. After a while, you’ll want to smack Mamako for enabling Masato’s entitled behavior. Then, you’ll want to smack the devs for apparently being content to let other players run muck-wild, brainwashing and enslaving other players, among other things. And so on and so forth.
There’s one more problem with the characters of Okaasan, the problem of how rotten behavior in general is universally dealt with. Several mothers and children in this show are downright abusive to their other half, and every single time the show doesn’t even slap the abuser on the wrist, sometimes going explicitly out of the way to say it isn’t their fault they’ve done such awful things. Every single time. Because I guess Mama’s love is all, amirite? Strangely, said characters are put on a bus before they get a chance to relapse...
Enjoyment: 1/10
There was no enjoyment to be found in this wasteland of a show. Okaasan’s writing is undeniably bottom-of-the-barrel garbage. The very best thing it can show for itself is its low-tier art and mediocre sound. Watching the show at all is an exercise in masochism.
So, in conclusion, who should watch this show?
If you are seriously horny for Mamako, then go for it, but don’t say I didn’t warn you that it’s bad.
If you came looking for a corny Isekai adventure, stay far away and don’t come back. There’s nothing funny or amusing about Okaasan in the slightest and it’ll only leave you feeling incredulous and angry.
If, for some reason, you purposely want to watch a terrible anime, then look no further. This is the one for you.
Overall, 1/10.
