TBF the anime of "My little sister can't possibly be this cute" wasn't bad. But holy shit the source material they had to work with really, really was.
Ha! Someone else watched that, now I don’t have to suffer in embarrassment alone. Honestly, it wasn’t even remotely as gross as it could have been, though I wouldn’t really call it “good”.
If that sounds weird to you onlookers, you should know that it’s not actually a story about incest (in season 1 at least, I didn’t watch season 2 and probably never will), but more so about otaku culture as a whole (which includes the imouto genre unfortunately). The biggest problem with the show is ironically the sister character. She’s just so annoying and she gets way too much screen time. The episodes that limit her presence are actually pretty good, but there aren’t enough of them to fully redeem the show in my eyes (episode 11 in particular made me want to vomit).
Yeah, I've seen it as well as I'm sure a lot of others here have as well.
It'd be a classic "popcorn" anime. By that I mean there's a large discrepancy between popularity and how highly it is rated by those who watched it. It's very popular (#112 on MAL by number of viewers), which, if you exclude sequels etc should put in the top ~100 most popular animes ever, at least in the West. However it has a fairly low score (#2356 by ratings). Like SAO, lots of people watched it but don't necessarily think it's all that great. I doubt all those people went in expecting a masterpiece of storytelling. Sometimes people just want to tune out with what they know will be cheesy shit.
I'd definitely say that if you didn't catch the second season then there's no real reason to tell you to go see it, unless you were totally hooked on the characters or somesuch, in which case you would already be onto that. More of the same, more or less, though the ending pissed some people off. Nothing in there to warrant sitting through 12 episodes, which you could better spend just picking some random obscure 12-episode anime and get more benefit from.
Plenty of better stupid comedies out there. A few random ones off the top of my head that don't get much mention. Saiki Kusuo no Ψ-nan, Sabagebu, Seitokai Yakuindomo, Binbougami Ga, Cuticle Detective Inaba. They'd all be more worthwhile than Oreimo if anyone's thinking of watching that.
